Protocols

Specificity / Sensitivity

GAPDH (14C10) Rabbit mAb (Alexa Fluor® 488 Conjugate) detects endogenous levels of total GAPDH protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide near the carboxy terminus of human GAPDH. This antibody was conjugated to Alexa Fluor® 488 under optimal conditions with an F/P ratio of 2-6.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of HeLa cells using GAPDH (14C10) Rabbit mAb (Alexa Fluor® 488 Conjugate) (green) compared to Rabbit (DA1E) mAb IgG Isotype Control (Alexa Fluor® 488 Conjugate) #2975 (red).

IF-IC

Confocal immunofluorescent analysis of C2C12 cells using GAPDH (14C10) (Alexa Fluor® 488 Conjugate) Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Description

This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometry and immunofluorescent analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated GAPDH (14C10) Rabbit mAb #2118.

Background

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) catalyzes the phosphorylation of glyceraldehyde-3-phosphate during glycolysis. Though differentially expressed from tissue to tissue (1), GAPDH is thought to be a constitutively expressed housekeeping protein. For this reason, GAPDH mRNA and protein levels are often measured as controls in experiments quantifying specific changes in expression of other targets. Recent work has elucidated roles for GAPDH in apoptosis (2), gene expression (3), and nuclear transport (4). GAPDH may also play a role in neurodegenerative pathologies such as Huntington and Alzheimer's diseases (4,5).
