Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.
Regulatory Status: RUO
Preparation And Storage: Preparation And Storage Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed.
Recommended Assay Procedures: Recommended Assay Procedures Immunofluorescent Staining and Flow Cytometric Analysis: The B27 antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IFN-γ producing cells within mixed cell populations. The FITC-conjugated B27 antibody (Cat. No. 554700/552887/561053) is especially suitable for these studies. For optimal immunofluorescent staining for flow cytometric analysis, the anti-cytokine antibody should be titrated (≤ 0.5 µg mAb/million cells). For specific methodology, please visit our website, http://www.bdbiosciences.com/us/s/resources and refer to the protocols under "Intracellular Flow". A useful control for demonstrating specificity of staining is the following: pre-block the paraformaldehyde-fixed/saponin-permeabilized cells with unlabeled B27 antibody (Cat. No. 554699/550011) prior to staining. The staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe. A suitable mouse IgG1 isotype control for assessing the level of background staining on paraformaldehyde-fixed/saponin-permeabilized human cells is FITC-MOPC-21 immunoglobulin (Cat. No. 554679); use at comparable concentrations to antibody of interest (e.g., ≤ 0.5 µg mAb/million cells). Neutralization: The NA/LE™ B27 antibody (Cat. No. 554698) is useful for neutralization of human IFN-γ bioactivity. A suitable NA/LE™ mouse IgG1 isotype control to match the NA/LE™ B27 antibody is the 107.3 antibody, Cat. No. 554721. IP/WB: The B27 antibody has been reported to be useful for immunoprecipitation studies. The B27 antibody has been reported not to bind to denatured IFN-γ. Please note that these applications are not routinely tested BD Biosciences Pharmingen.
