Mouse (G3A1) mAb IgG1 Isotype Control (Alexa Fluor® 555 Conjugate) #9641
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Mouse (G3A1) mAb IgG1 Isotype Control (Alexa Fluor® 555 Conjugate) is not directed against any known antigen. It functions as an isotype control for mouse IgG1 monoclonal antibodies.
Source / Purification
Confocal immunofluorescent analysis of HeLa cells using β-Catenin (L54E2) Mouse mAb (Alexa Fluor® 555 Conjugate) #5612 (red, left) compared to concentration matched Mouse (G3A1) mAb IgG1 Isotype Control (Alexa Fluor® 555 Conjugate) (right). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
This Cell Signaling Technology (CST) antibody is conjugated to Alexa Fluor® 555 fluorescent dye under optimal conditions and tested in-house for direct immunofluorescent analysis in human cells.
Isotype control antibodies are used to estimate the nonspecific binding of target primary antibodies due to Fc receptor binding or other protein-protein interactions. An isotype control antibody should have the same immunoglobulin type and be used at the same concentration as the test antibody.
