Immunohistochemical Profiling of Immune Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunohistochemical staining for CD4+ T cell, CD68+ macrophages as APCs and tubular Kim-1 and TLR4 was performed on 6-μm periodate lysine paraformaldehyde-fixed sections [21 (link)]. CD11c+ and F4/80+ cells as APCs (DCs, CD11c+ and pan-macrophages, F4/80+ cells) were identified in 4-ìm-thick formalin-fixed sections. The numbers of these cells were assessed in 10 fields per slide at ×400 magnification, and the results are expressed as cells per high-power field (c/hpf). The primary monoclonal antibodies used were rat monoclonal antibody GK1.5 for CD4+ T cells (Pharmingen, San Diego, CA, USA), for APCs with CD68+ (Serotec, Oxford, U.K.), F4/80 hybridoma culture supernatant (HB 198; American Type Culture Collection, Manassas, MD, USA) and mouse monoclonal antibody for CD11c+ (Abcam, Cambridge, U.K.), rabbit polyclonal antibody TLR4 (Novus Biologicals, Littleton, CO, USA) and rat monoclonal antibody Tim-1 (R & D Systems, Minneapolis, MN, USA).

TIM-3 (Q8TDQ0) was purchased from LifeSpan Biosciences (LS-G97947). CD43 (P16150) and TIM-1 recombinantly expressed in NS0 cells were purchased from R&D systems (9680-CD,1750-TM). C1-Inh (P05155) and fibronectin (P02751) isolated from human plasma were purchased from Sigma Aldrich (E0518, F1056). Bovine Fetuin-A (P12763) was purchased from Promega (V4961). GP1bɑ (P07359) was isolated as described previously8 . The plasmids for His-tagged pET28a-SmEnhancin and recombinant StcE protein were kindly provided by the Bertozzi laboratory.

Western Blot Analysis of Tim-1 and Tim-3

Check if the same lab product or an alternative is used in the 5 most similar protocols
Prior to Western blot, total protein was quantified using bicinchoninic assay (BCA, Pierce). A total of 20 mg protein per lane was loaded onto a denaturing SDS-PAGE gel (BioRad) and subsequently transferred to a nitrocellulose membrane. This membrane was blocked in 5% milk made in Tris-buffered saline and Tween-20 (TBS-T). Blots were probed for Tim-1 (10 μg/ml, R&D Systems), Tim-3 (0.1 μg/ml, R&D Systems) or b-actin (1:3000, Sigma) overnight at 4°C. Corresponding secondary antibody conjugated to HRP was used (1:5000, GE Amersham), visualizing bands using ECL reagents (Perkin-Elmer) on an Amersham Imager 600 (GE Amersham) with densitometry analysis using ImageJ.

Efferocytic Receptor Modulation in Gingiva

Antibodies to the following mouse efferocytic receptors (or isotype controls) were locally microinjected (each at 5 μg) to the gingiva of WT mice, which were sacrificed 72h later to dissect gingival tissue for measuring cytokine mRNA expression by quantitative real-time PCR (section 2.6): TIM-1 (affinity-purified polyclonal IgG; R&D Systems); TIM-4 (clone RMT4-53) and IgG2b isotype control (BioXcell); CD11b (clone M1/70) and IgG2b isotype control (both from R&D Systems); CD14 (clone Sa14-2, IgG2a; eBioscience/Thermo-Fisher); CD36 (clone MF3, IgG2a; eBioscience/Thermo-Fisher); Mer (clone 108921) and IgG1 isotype control (both from R&D Systems).

Immunohistochemical Analysis of Immune Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunohistochemical staining for CD4+ T-cells, Gr-1+ cells as neutrophils, and tubular Kim-1 (kidney injury molecule-1) was performed on 6 μm periodate lysine paraformaldehyde-fixed sections [36 ]. Here, CD11c+ cells and F4/80+ cells were examined as antigen-presenting cells (APCs; DCs, CD11c+ and pan-macrophages, F4/80+ cells), and phospho c-Jun+ cells were identified in 4 μm-thick formalin-fixed sections. The numbers of these cells were assessed in 10 fields per slide at ×400 magnification, and the results are expressed as cells per high-power field (c/hpf). The primary monoclonal antibodies used were rat monoclonal antibody GK1.5 for CD4+ T-cells (Pharmingen, San Diego, CA, USA), F4/80 hybridoma culture supernatant (HB 198; American Type Culture Collection, Manassas, MD, USA), mouse monoclonal antibody for CD11c+ cells (Abcam, Cambridge, U.K.), RB6–8C5 for neutrophils (anti-Gr-1; DNAX, Palo Alto, CA), and rat monoclonal antibody Tim-1 (R&D Systems, Minneapolis, MN, USA). Isotype-matched irrelevant monoclonal antibodies were used as controls.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
