免疫原
Human Granzyme B
简单描述
The GB11 antibody specifically reacts with human granzyme B, a serine protease of approximately 32 kDa.
Granzyme B is stored in the granules of cytotoxic T lymphocytes and NK cells along with the pore-forming protein perforin. In the classic model of target cell lysis, perforins create holes in the target cell membrane allowing entrance of granzymes. Granzyme B has been shown to act on specific substrates including caspase-3, -7, -9, and -10 which in turn give rise to enzymes that mediate apoptosis. Granzyme B may also be involved in the hydrolysis of extracellular matrix components.
Detectable levels of granzyme B have been detected in sera from healthy volunteers. The immunogen used to generate the GB11 hybridoma was human granzyme B isolated from an NK cell line.

产品详情
PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Flow cytometric analysis of Granzyme B expression by peripheral blood lymphocytes. Human PBMC were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained with Alexa Fluor® 647 Mouse Anti-Human CD8 (Cat. No. 557708) and either PE Mouse Anti-Human Granzyme B Antibody (Cat. No. 561142, Left Panel) or PE Mouse IgG1 Isotype Control (Cat. No. 555749, Right Panel) by using BD Biosciences Pharmingen's Staining Protocol. Two-color flow cytometric dot plots showing the correlated expression patterns of CD8 and Granzyme B or Mouse IgG1 Isotype Control staining were derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry was performed using a BD LSR™ II Flow Cytometer System.
