Isotype control antibodies, to estimate the nonspecific binding of target. Use at concentrations comparable to those of the specific antibody of interest.
Flow cytometric analysis of C57BL/6 mouse splenocytes labeling Rat mAb IgG2b Isotype Control at 1/20 dilution (1 μg) / (Left panel) compared with CD8α antibody at 1/200 (1 μg) dilution (S0B0498) / (Right panel). Goat Anti-Rat IgG Alexa Fluor 488 was used as the secondary antibody. Then cells were stained with CD4 - Brilliant Violet 421™ separately. Gated on total viable cells.
IHC shows negative staining in paraffin-embedded mouse spleen. Rat mAb IgG2b Isotype Control was used at 1/80 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
