Ovaries were dissected in PBS, fixed for 20 min in 4% paraformaldehyde (PFA) in PBS, washed for 45 min in PBS/0.1% Triton X‐100 (PBST) and blocked for 30 min in 5% normal goat serum (NGS)/PBST. Primary antibodies were diluted in NGS/PBST, and samples were incubated overnight at 4°C.
Primary antibodies used were FITC‐conjugated anti‐GFP (1:400; Abcam), rat anti‐Crb (1:300, a gift from U.Tepass), anti‐Ex (gift from R. Fehon), rabbit anti‐Kib (1:200, Genevet et al, 2010 (link)), rabbit anti‐aPKCζ (C20) (1:250 Santa Cruz), anti‐pWts (gift from K. Irvine), anti‐Rab5 (DSHB), anti‐Rab7 (DSHB), anti‐Rab11 (DSHB), anti‐alpha‐spec (DSHB). Secondary antibodies (goat Alexa Fluor 488, 546, 647; Invitrogen) were used at 1:500 for 2 h at RT, and samples were mounted in Vectashield (Vector Laboratories).

Following antibodies were used for confocal microscopy. Conformation dependent LIBS anti-α5 antibody clone SNAKA-51 was from Millipore. Phycoerythrin-conjugated anti-α5 antibody (clone SAM-1) was from BioLegend. Anti-β1 antibody clone TS2/16 was produced from the hybridoma cell line TS2/16.2.1 (HB-243, ATCC) and purified on protein-G-sepharose column (Pierce). Anti-αv antibody, clone PLW7, was from Santa Cruz Biotechnology, anti-fibronectin antibody, clone 10, was from BD Biosciences, anti-pFAK-tyr397, clone 141-9 from Life Technologies. Fluorescently labeled secondary antibodies were purchased from Invitrogen (Alexa Fluor -488; -546; -647). Dapi was purchased from Santa Cruz Biotechnology. Human fibronectin stabilized solution was purified as described in Reference 35. Cell culture medium and reagents were from Lonza. All other reagents were of molecular biology quality.

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.
