WB
Western blot analysis of RAB8A on different lysates with Rabbit anti-RAB8A antibody at 1/500 dilution.
Lane 1: NIH/3T3 cell lysate,
Lane 2: RAW264.7 cell lysate,
Lane 3: C2C12 cell lysate,
Lane 4: L6 cell lysate,
Lysates/proteins at 30 µg/Lane.
Exposure time: 2 minutes 16 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 1/500 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1:100,000 dilution was used for 1 hour at room temperature.
ICC/IF
Immunocytochemistry analysis of HeLa cells labeling RAB8A with Rabbit anti-RAB8A antibody at 1/100 dilution.
Cells were fixed in 4% paraformaldehyde for 10 minutes at 37 ℃, permeabilized with 0.05% Triton X-100 in PBS for 20 minutes, and then blocked with 2% negative goat serum for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-RAB8A antibody at 1/100 dilution in 2% negative goat serum overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (488) was used as the secondary antibody at 1/1,000 dilution. Nuclear DNA was labelled in blue with DAPI.
Beta tubulin (red) was stained at 1/200 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 HeLa cells labeling RAB8A.
Cells were fixed and permeabilized. Then stained with the primary antibody (1ug/ml) (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 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
RAB8A was immunoprecipitated from 0.2 mg HeLa cell lysate with Rabbit anti-RAB8A antibody at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using Rabbit anti-RAB8A antibody at 1/1,000 dilution. Anti-Rabbit IgG for IP Nano-secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.
