Flow cytometric analysis of Jurkat cells, untreated (green) or LY294002- and wortmannin-treated (blue), using Phospho-Akt (Ser473) (193H12) Rabbit mAb (Alexa Fluor® 647 Conjugate) #2337 compared to Rabbit IgG Isotype Control (Alexa Fluor® 647 Conjugate) (red).Learn more about how we get our images.
Note: This control antibody must be diluted to the same concentration (not dilution) as the specific antibody in analysis. See Directions on Use.
Important Note on Use: This control antibody must be diluted to the same concentration (not dilution) as the specific antibody in analysis. Higher background fluorescence may result if excessive amounts of rabbit IgG isotype control are used. Do not use this antibody at 1:50 dilution in the same way as recommended for other CST Alexa Fluor® conjugated antibodies.
Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.
The purified antibody is not directed against any known antigen. It functions as an isotype control for rabbit antibodies.
The antibody was isolated from naive rabbit sera and purified by affinity chromotography. The antibody was conjugated to Alexa Fluor® 647 under optimal conditions with a F/P ratio of 2-6.
Rabbit IgG was conjugated to Alexa Fluor® 647 fluorescent dye under optimal conditions, and tested in-house for direct flow cytometric analysis of human and mouse cells. Alexa Fluor® dye is maximally excited by red light (e.g. 633 nm He-Ne laser). Antibody conjugated of the Alexa Fluor® 647 dye produce far-red-fluorescence emission with a peak at 655 nm.
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.
