WB
Western blot analysis of TIM 3 on different lysates with Rabbit anti-TIM 3 antibody at 1/2,000 dilution.
Lane 1: RPMI 8226 cell lysate (20 µg/Lane)
Lane 2: HT-29 cell lysate (negative) (20 µg/Lane)
Lane 3: HUT 102 cell lysate (20 µg/Lane)
Exposure time: 40 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 RPMI 8226 (positive) and HT-29 (negative) labeling TIM 3 with Rabbit anti-TIM 3 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-TIM 3 antibody at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 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 (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.
FC
Flow cytometric analysis of HT-29 (left, negative) and RPMI 8226 (right, positive) cells labeling TIM 3.
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
TIM 3 was immunoprecipitated from 0.2 mg RPMI 8226 cell lysate with abbit anti-TIM 3 antibody at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using abbit anti-TIM 3 antibody at 1/2,000 dilution. Mouse Anti-Rabbit IgG kappa light chain secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.
Lane 1: RPMI 8226 cell lysate (input),
Lane 2: abbit anti-TIM 3 antibody IP in RPMI 8226 cell lysate,
Lane 3: Rabbit IgG instead of abbit anti-TIM 3 antibody in RPMI 8226 cell lysate.
Blocking/Dilution buffer: 5% NFDM/TBST
Exposure time: 59 seconds.
