The recombination assays were fixed and permeabilized as described above. Then blocked overnight at 4°C in 10% DS, 1% BSA, 1.8% IgG MOM and 0.1% PBST. Primary antibodies were incubated overnight at 4°C in 16% MOM and 0.1% PBST: Pna-Rhodamine (1:75), rabbit anti-K5 (1:2000), mouse anti-Tubb3 (1:200), rabbit anti-Ecadherin (1:100), rat anti-perlecan (1:100). Primary antibodies for human-mouse recombination incubated overnight at 4°C in 16% MOM and 0.1% PBST: mouse anti-Ki67 (1:100), goat anti-Kit (1:100), mouse anti-human nuclear antigen (1:100, Millipore), rabbit anti-Ecadherin (1:100), mouse anti-Tubb3 (1:200), rat anti-integrinβ1 (1:100, Gift of Dr. K.M. Yamada) and rabbit anti-K5 (1:2000). Secondary antibodies incubated for one hour at room temperature in 16% MOM protein and 0.1% PBST: 1:2000 Hoescht, anti-Rabbit cy3 and cy5 (1:200), anti-Mouse cy2 (1:100), anti-goat cy 5 (1:200), and anti-rat cy3 and cy2 (1:200).

Astrocytes were seeded in a 4‐well chamber slide (Nunc, Cat# 177437) at a density of 30,000 cells per well. Cells were fixed after 24 h, using 4% paraformaldehyde, washed thrice with 1X PBS, blocked, and permeabilized using 4% BSA containing 0.4% Triton‐X 100. The cells were then incubated with antibodies, mouse anti‐coronin 1A (Santa Cruz Biotechnology, 1:100, Cat# sc‐100925, RRID:AB_2291951), mouse anti‐Ki 67 (Millipore, 1:1000, Cat# MAB4190, RRID:AB_95092), mouse anti‐vimentin (Santa Cruz Biotechnology, 1:1000, Cat# sc‐6260, RRID:AB_628437), overnight at 4°C, or anti‐GFAP (Dako, 1:1000, Cat# Z0334, RRID:AB_10013382) for 1 h at 25°C. The cells were then washed thrice with 1X PBS and incubated with appropriate fluorophore‐tagged secondary antibodies (Invitrogen, 1:1000). The wells were washed thrice with 1X PBS and mounted using Hardset mounting media with DAPI (Vector Labs, Cat# H‐1500). For each group, a minimum of five images were captured from random fields using the AxioImager Z1 microscope (Zeiss).

Immunohistochemical Profiling of Liver Metastases

Check if the same lab product or an alternative is used in the 5 most similar protocols
Liver sections (7 µm thick) were fixed in cold acetone, and stained with hematoxylin/eosin staining. For triple immunohistochemical analyses, sections were reacted with rat anti-mouse CD31 (1:100, Dako), rabbit anti-mouse Desmin (1:200, Dako), and mouse anti-human α-SMA (1:50, Sigma-Aldrich) followed by the appropriate fluorescent secondary antibodies (n = 72). Serial sections were incubated with either rat anti-F4/80 (1:100, BIO-RAD) (n = 36) or mouse anti-Ki67 (1:200; Sigma-Aldrich) (n = 36), followed by appropriate fluorescent secondary antibodies. Irrelevant appropriate immunoglobulins were used as negative controls. Metastases were microphotographed using a Zeiss Axioskop fluorescence microscope under the same conditions. Specific immunostaining was quantified using FIJI-ImageJ software. Results were expressed as the percentage of specifically colored tissue area relative to the whole micrometastatic foci area.

Proliferative Potential of SurR9-C84A in Differentiated SK-N-SH Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
To evaluate the proliferative potential of SurR9-C84A on differentiated SK-N-SH cells, immunofluorescence for the proliferative markers PCNA and Ki67 were studied. Cells were seeded at 105 cells/well in BD Falcon eight-well culture slides following the protocol described for the undifferentiated cells. After treatment with SurR9-C84A, the differentiated cells were incubated with mouse monoclonal anti-PCNA and mouse anti-Ki67 (1:100; Sigma-Aldrich) for 1 hour at 37°C. FITC-labeled rabbit antimouse and goat antirabbit (1:100) were used as secondary antibodies. The cell nucleus was stained with PI (1:500) for 30 minutes, and further imaging was carried out using the Leica SP5 confocal microscope at 40× magnification.

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.
