Neutralization Activity: This antibody has been reported to be useful for the neutralization of recombinant mouse IL-4. Neutralization activity may be measured with a proliferation assay using 1 ng/mL recombinant mouse IL-4 (Cat. No. 550067) to stimulate D36 cells at 1x10^5 cells/mL as indicator cells (i.e. preincubation of the antibody with recombinant mouse IL-4 for 60 minutes). 50% Neutralization (ND50) at 1.5 - 75 ng/mL >95% Neutralization at 0.2 - 1.1 µg/mL
Purification
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Sterility
0.2 μm filtered
Endotoxin Level
Endotoxin level is ≤ 0.01 EU/μg (≤ 0.001 ng/μg) of protein as determined by the LAL assay.
ELISA: The purified format of BVD4-1D11 antibody (Cat. No. 554387) can be useful as a capture antibody in a sandwich ELISA for measuring mouse IL-4. Purified BVD4-1D11 antibody can be paired with the biotinylated BVD6-24G2 antibody (Cat. No. 554390) as the detecting antibody, with recombinant mouse IL-4 (Cat. No. 550067) as the standard. For testing mouse IL-4 in complex biological fluids, such as serum or plasma, investigators may wish to consider using the BD OptEIA™ Mouse IL-4 Set (Cat. No. 555232).
