Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-VAMP8/EDB antibody [EP2629Y] - BSA and Azide free (AB227984)

Immunohistochemical analysis of Human lacrimal gland tissue staining VAMP8/EDB with unpurified ab76021.

Antigen retrieval was performed using antigen retrieval solution in a microwave. Sections were blocked with 10 goat serum for 30 minutes and incubated with primary antibody (1/100) overnight at 4°C. Staining was detected using DAB.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab76021).

Western blot - Anti-VAMP8/EDB antibody [EP2629Y] - BSA and Azide free (AB227984)

False colour image of Western blot : Anti-VAMP8/EDB antibody [EP2629Y] staining at 1/10000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab76021 was shown to bind specifically to VAMP8/EDB. A band was observed at 11 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in VAMP8 knockout cell line ab266293 (knockout cell lysate ab257791). To generate this image, wild-type and VAMP8 knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged.Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

This data was developed using the same antibody clone in a different buffer formulation (ab76021).

Lanes 1 - 4 : Merged signal (red and green). Green - ab76021 observed at 13 kDa. Red - loading control, ab7291 (Mouse anti-Alpha Tubulin [DM1A] observed at 55kDa.

ab76021 was shown to react with VAMP8/EDB in wild-type A431 cells in western blot. Loss of signal was observed when VAMP8 knockout sample was used. Wild-type and VAMP8 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% milk in TBS-T (0.1% Tween^®) before incubation with ab76021 and ab7291 (Mouse anti-Alpha Tubulin [DM1A] overnight at 4°C at a 1 in 10000 Dilution and a 1 in 20000 dilution respectively.
