WB
Western blot analysis of COL5A1 on Saos-2 cell lysates with Rabbit anti-COL5A1 antibody at 1/2,000 dilution.
Lysates/proteins at 20 µg/Lane.
Exposure time: 20 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
ICC/IF
Immunocytochemistry analysis of Saos-2 cells labeling COL5A1 with Rabbit anti-COL5A1 antibody at 1/100 dilution.
Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-COL5A1 antibody at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.
Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (594) was used as the secondary antibody at 1/1,000 dilution.
FC
Flow cytometric analysis of Saos-2 cells labeling COL5A1.
Cells were fixed and permeabilized. Then stained with the primary antibody (1/1,000) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
IP
COL5A1 was immunoprecipitated from 0.2 mg Saos-2 cell lysate with Rabbit anti-COL5A1 antibody at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using Rabbit anti-COL5A1 antibody at 1/1,000 dilution. Mouse anti Rabbit IgG heavy chain (Fc) secondary antibody at 1/10,000 dilution was used for 1 hour at room temperature.
