Recommended Assay Procedures: Recommended Assay Procedures Blocking Control for Intracellular Staining: The purified BVD2-21C11 antibody (Cat. No. 554503) can be used as a blocking control to demonstrate specificity of human GM-CSF staining by the PE-BVD2-21C11 (Cat. No. 554507). To perform this control, the fixed/permeabilized cells (~ 1 million) can be incubated with 1 - 10 µg of unlabeled BVD2-21C11 antibody (Cat. No. 554503) for 20 minutes at 4°C, prior to staining with PE-BVD2-21C11 antibody (eg, 0.1 - 0.5 µg mAb/ 1 million cells). The intracellular cytokine staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe.  For specific methodology, please visit the protocols section under "Cytokines (Intracellular Staining)" at our website: http://www.bdbiosciences.com/us/s/resources. ELISA Detection: The biotinylated BVD2-21C11 antibody, Cat. No. 554505, is useful as a detection antibody for a sandwich ELISA for measuring human GM-CSF protein levels.  Biotinylated BVD2-21C11 antibody can be paired with the purified BVD2-23B6 antibody (Cat. No. 554502) as the capture antibody, with recombinant human GM-CSF (Cat. No. 550068) as the standard. For specific methodology please visit the protocols sections or the chapter on ELISA in the Immune Function Handbook, both of which are posted on our web site, www.bdbiosciences.com. This ELISA pair is recommended primarily for measuring cytokine from experimental cell culture systems. Note : For testing GM-CSF in serum or plasma, our BD OptEIA™ ELISA Set (Cat. No. 555126) is recommended. IP : The purified BVD2-21C11 antibody has been reported to be useful for immunoprecipitation studies.  Please note that this application is not routinely tested at BD Biosciences Pharmingen.
