Immunofluorescence Detection of CPAF in Chlamydia
Cited 27 times
Immunofluorescence detection of CPAF in chlamydia-infected cells was carried out as described previously 67. In brief, HeLa cell monolayer was infected with Chlamydia trachomatis L2 for 30 h. The monolayer, after it was fixed with paraformaldehyde (Sigma-Aldrich) and permeabilized with Saponin (Sigma-Aldrich), was costained with Hoechst 32258 (blue), anti-MOMP antibody MC22 (probed with an FITC-conjugated, mouse IgG3-specific secondary antibody), and anti-CPAFn antibody 54b (probed with a Cy3-conjugated, mouse IgG1-specific secondary antibody). Images were acquired individually for each stain in gray using a Cooker digital camera connected to an AX70 Olympus microscope, and the single-color images were merged in frame into the triple-color image using the software Image Pro.

ELISA Antibody Quantification from Dried Blood Spots
Cited 25 times
Microtitre plates (Immulon 4HBX, Thermo) were coated with recombinant MSP-119.GST (to which antibodies are predominantly of the IgG1 subclass [36 (link)]) or MSP-2.GST (to which antibodies are predominantly IgG3 [36 (link)]) and blocked with 1% (w/v) skimmed milk powder. Samples were assayed as described previously[36 (link),37 (link)] except that coating antigens, test samples and secondary antibody conjugate were each added in a total volume of 50 μl per well. Ten microliters of the antibody-containing eluate of each spot were added to individual wells of the coated and blocked microtitre plate together with 40 μl blocking buffer to give a final concentration of 1:1,000 with respect to the corresponding plasma sample. Each plate included a five-fold dilution series (1:50 to 1:156,250 final dilutions) of a standard African hyperimmune plasma pool. Bound antibodies were detected with either rabbit anti-human-IgG -HRP (Dako, Ely, UK), or sheep-anti-human IgG1 or IgG3-HRPconjugates (The Binding Site, Birmigham, UK) secondary antibodies and developed with o-phenylenediamine-H2O2.
A titration curve was fitted to the ODs obtained for the standard plasma dilutions by least squares minimisation using a three variable sigmoid model and the solver add-in in Excel (Microsoft), assuming an arbitrary value of 1000 Units/ml of antibody against each antigen in the standard pool. OD values for the spot extracts were converted to units/ml using this fitted curve.
Recoveries for blood spots were estimated as follows (full details in Additional file 1): serum or plasma ODs were converted to concentrations as above, the concentrations were multiplied by a recovery factor and then converted back to 'corrected' ODs – the ODs which would have been obtained if the serum or plasma had been more dilute. The value of the recovery factor was then optimized by weighted least squares minimisation comparing the actual ODs for the blood spots and the corrected OD values for serum or plasma, using the solver add-in in Excel™.

Genomic DNA Isolation and Amplification
Cited 10 times
Genomic DNA was isolated from B cells, either resting or cultured with LPS for 4 d. Cell pellets were incubated with proteinase K (0.5 mg/ml), RNaseA (100 μg/ml), and SDS (0.5%) in STE (0.1 M NaCl, 20 mM Tris, 1 mM EDTA) for 2 h at 37°C, followed by 3–4 extractions with phenol/chloroform (1:1) and precipitation with 0.3 M sodium acetate, pH 7, and ethanol. DNA was wound out on glass rods and resuspended in TE, pH 8. The germline Sγ3 segment was amplified by PCR from resting purified B cells from WT(129 × B6) mice for comparison to Sμ-Sγ3 junctions from cells induced to switch to IgG3. Expand HiFidelity Taq polymerase (Roche Laboratories) was used with the following primers: g3–1 (5′CAGGCTAAGATGGATG- CTACAGGG-3′) (MUSIGHANA 404–427) and g3–2 (5′TAC- CCTGACCCAGGAGCTGCATAAC-3′) (MUSIGHANA 2603–2628) to amplify the 2.22-kb fragment of germline Sγ3. Sμ-Sγ3 junctions were amplified by PCR using Expand Long Template Taq polymerase (Roche Laboratories) and the primers μ3-H3 (5′AACAAGCTTGGCTTAACCGAGATGAGCC-3′) and g3–2 (above). The germline Sμ sequence was deduced by comparing the sequences of a large number of Sμ-Sγ3 junctions from wild-type mice. For the sequence analyses, the wild-type sequences from the corresponding littermates were used.

Detecting Autoantibodies via ELISA
Autoantibodies were detected using ELISA method, as described by Józsi and Uzonyi (36 (link)). Briefly, FH, FB, C3b, FI in 5 µg/ml, MBL and C1q in 2 µg/ml and HSA or alpha-1 antitrypsin as negative controls were immobilized on microtiter plates. After blocking with 5% BSA in DPBS-0.1% Tween-20, serum samples were added in DPBS-0.1% Tween-20 at a dilution of 1:50 for 1 hour at RT. To detect autoantibodies against solid phase C3 convertase of the alternative pathway (C3bBbP), the convertase was built up (see below) and incubated with serum samples diluted 1:50. The bound autoantibodies were detected with HRP-conjugated goat anti-human IgG, anti-human IgA or anti-human IgM. Color reaction was developed by adding TMB solution (BioLegend). After stopping with H2SO4, absorbance was measured at 450 nm and at 620 nm as reference wavelength. To detect anti-MBL autoantibodies, serum samples were diluted in DPBS containing 10 mM EDTA. In the case of detecting anti-C1q autoantibodies, serum samples were diluted in DPBS containing 1 M NaCl to avoid interaction of C1q globular heads with IgG Fc parts. Samples were accepted as positive if the mean OD value for the investigated protein was at least two-fold greater than the mean OD value for the negative control protein alpha-1 antitrypsin. The isotypes of the autoantibodies were determined using monoclonal antibodies specific for IgG1, IgG2, IgG3, IgG4, IgGκ and IgGλ.

Isolation and Expansion of IPF Progenitor Cells
For isolation of IPF and control MPCs, primary IPF mesenchymal cells were labeled with mouse anti–human SSEA4 antibody conjugated to Alexa Fluor 647 (clone MC-813-70; catalog 560796; BD Biosciences) and mouse anti–human CD44 conjugated to FITC (clone IM7; catalog 103006; BioLegend). Cells were sorted on a FACS Aria Cell Sorter (BD Biosciences). Cells that were SSEA4+ and CD44+ (relative to mouse IgG3 κ isotype control conjugated to Alexa Fluor 647 and mouse IgM κ isotype control conjugated to FITC, respectively) (clone J606, catalog 560803 [BD Biosciences] and catalog 402207 [BioLegend]) were collected. To generate sufficient numbers of MPCs for the in vivo mouse studies, SSEA4+CD44+ cells were expanded by culture in DMEM + 10% FCS for 7 days prior to use. The resulting MPC cultures were reanalyzed for SSEA4 expression by FACS analysis and for colony formation in vitro. In total, 97% of day 7 MPCs were SSEA4+ and formed colonies in methylcellulose indicating retention of progenitor self-renewal properties during in vitro expansion.

Quantification of Antibody Responses by ELISA
Standardized ELISAs were used to quantify serum RH5.1–specific IgG1, IgG2, IgG3, IgG4, IgA, IgA1, IgA2, and IgM responses in vaccinees. Nunc MaxiSorp flat-bottom ELISA plates (44-2404-21, Invitrogen) were coated overnight with 5 μg/mL of RH5.1 protein in PBS. Plates were washed with washing buffer composed of PBS containing 0.05% TWEEN 20 (P1379, Sigma-Aldrich) and blocked with 100 μL of Blocker Casein in PBS (37582, Thermo Fisher Scientific). After removing blocking buffer, standard curve and internal controls were created in casein using a pool of high-titre volunteer plasma, specific for each isotype or subclass being tested, and 50 μL of each dilution was added to the plate in duplicate. Test samples were diluted in casein to a minimum dilution of 1:50, and 50 μL was added in triplicate. Plates were incubated for 2 hours at 37°C and washed in washing buffer. An alkaline phosphatase–conjugated secondary antibody from Southern Biotech was diluted at the manufacturer’s recommended minimum dilution for ELISA in casein. The antibody used was dependent on the isotype or subclass being assayed and were as follows: mouse anti–human IgG1 Fc-AP (catalog 9054-04), IgG2 Fc-AP (catalog 9060-04), IgG3 hinge-AP (catalog 9210-04), IgG4 Fc-AP (catalog 9200-04), IgA1-AP (catalog 9130-04), and IgA2-AP (catalog 9140-04) and goat anti–human IgA-AP (catalog 2050-04) and IgM-AP (catalog 2020-04). In total, 50 μL of the secondary antibody dilution was added to each well of the plate and incubated for 1 hour at 37°C. Plates were developed using PNPP alkaline phosphatase substrate (N2765, Sigma-Aldrich) for 1–4 hours at 37°C. Optical density at 405 nm was measured using an ELx808 absorbance reader (BioTek) until the internal control reached an OD405 of 1. The reciprocal of the internal control dilution giving an OD405 of 1 was used to assign an AU value of the standard. Gen5 ELISA software v3.04 (BioTek) was used to convert the OD405 of test samples into AU values by interpolating from the linear range of the standard curve fitted to a 4-parameter logistics model. Any samples with an OD405 below the linear range of the standard curve at the minimum dilution tested were assigned a minimum AU value according to the lower limit of quantification of the assay.
