For fluorescent immunohistochemistry (IHC) of fibronectin and integrin β1,
deparaffinized slides were subjected to antigen retrieval in boiled sodium
citrate buffer solution (pH 6.0) for 10 min, then blocked for 20 min in blocking
buffer (5% bovine serum albumin and 0.01% Triton X-100 in phosphate buffer
solution (PBS; Sigma). After blocking, samples were incubated with rabbit
polyclonal anti-fibronectin (Abcam, ab2413, 1:300) and rabbit polyclonal
anti-integrin β1 (Abcam, ab183666, 1:300) overnight at 4°C. Alexa Fluor 594 goat
anti-rabbit IgG (Life Technologies, USA, 1:500) were used to detect primary
antibodies, and then counterstained with 4′,6-diamidino-2-phenylindole (DAPI;
Invitrogen). Immunofluorescent images were captured using a Leica TCS SP5
confocal microscope (Leica). The expression intensity was measured using the
Image-Pro Plus 6.0 program (Media Cybernetics, Rockville, MD, USA).

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.
