CCR7 Recombinant Rabbit Monoclonal Antibody [SR36-04]

☑ Knockdown (KD)

All lanes: Western blot analysis of CCR7 with anti-CCR7 antibody (ET1602-22) at 1:5,000 dilution.
Lane 1/2: Wild-type Hela whole cell lysate (10 µg).
Lane 3/4: CCR7 fragment 1 knockdown Hela whole cell lysate (10 µg).
Lane 5/6: CCR7 fragment 2 knockdown Hela whole cell lysate (10 µg).

ET1602-22 was shown to specifically react with CCR7 in wild-type Hela cells. Weakened was observed when CCR7 knockdown sample was tested. Wild-type and CCR7 knockdown samples were subjected to SDS-PAGE. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM in TBST for 1 hour at room temperature. The primary antibody (ET1602-22, 1/500) and Loading control antibody (Rabbit anti-GAPDH, ET1601-4, 1/10,000) was used in 5% BSA at room temperature for 2 hours. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HA1001) at 1:200,000 dilution was used for 1 hour at room temperature.

Immunocytochemistry analysis of Daudi cells labeling CCR7 with Rabbit anti-CCR7 antibody (ET1602-22) at 1/250 dilution.

Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 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-CCR7 antibody (ET1602-22) at 1/250 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488, HA1121) 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 (M1305-2, red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594, HA1126) was used as the secondary antibody at 1/1,000 dilution.
