機能
This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. Seems to be linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. Cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis. -

Granzyme B was immunoprecipitated from 0.35 mg mouse spleen cells (treated with 2.5ug/ml Concanavalin A for 72h) whole cell lysate with ab255598 at 1/30 dilution. Western blot was performed on the immunoprecipitate using ab255598 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used as the secondary antibody at 1/5000 dilution.
Lane 1: Mouse spleen cells (treated with 2.5ug/ml Concanavalin A for 72h) whole cell lysate 10μg
Lane 2: ab255598 IP in mouse spleen cells (treated with 2.5ug/ml Concanavalin A for 72h) whole cell lysate
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab255598 in mouse spleen cells (treated with 2.5ug/ml Concanavalin A for 72h) whole cell lysate.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 10 seconds

All lanes : Anti-Granzyme B antibody [EPR22645-206] (ab255598) at 1/1000 dilution
Lane 1 : Untreated mouse splenocyte lysate
Lane 2 : Mouse splenocytes treated with 2.5µg/ml concanavalin for 72 hours, lysate
Lysates/proteins at 20 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution (Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated)
Predicted band size: 27 kDa
Observed band size: 28,65 kDa why is the actual band size different from the predicted?
Exposure time: 8 secondsThe expression of Granzyme B is elevated in stimulated splenocytes. Granzyme B forms complex with its protease inhibitor.
The molecular weight observed is consistent with what has been described in the literature (PMID: 8663264, 17116752, 21919028, 9774654).
Blocking/Diluting buffer and concentration: 5% NFDM/TBST.
