Confocal immunofluorescent analysis of HT-29 cells using β-Tubulin (9F3) Rabbit mAb (Alexa Fluor® 555 Conjugate) #2116 (red, left) compared to concentration matched Rabbit (DA1E) mAb IgG XP® 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 and tested in-house for direct immunofluorescent analysis in human cells.
Note: This control antibody must be diluted to the same concentration (not dilution) as the specific antibody in analysis. See Directions for Use.
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.
Rabbit (DA1E) mAb IgG XP® Isotype Control (Alexa Fluor® 555 Conjugate) is not expected to recognize any specific antigen. It functions as an isotype control for rabbit monoclonal antibodies.
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.
