Biological Activity: Proliferation is measured using MC/9 indicator cells pulsed with MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide).
Specific Activity: 0.3 - 2.0 x 10^8 Units/mg
Unit is defined as the amount of material required to stimulate a half-maximal response at cytokine saturation.
ED50: 50 - 300 pg/mL - Attributs du produit
- Recombinant mouse IL-4 is supplied as a frozen liquid comprised of 0.22 µm sterile-filtered aqueous buffered solution, pH 7.2, containing glycerol and 2.0 mg/mL biotechnology grade, low endotoxin bovine serum albumin, with no preservatives. Recombinant mouse IL-4 was purified by immunoaffinity chromatography and was found to be > 95% pure by SDS-PAGE analysis, and an absorbance assay based on the Beers Lambert Law.

- Indications d'application
- ELISA Standard: Mouse IL-4 is useful as a quantitative standard for measuring mouse IL-4 protein levels in an IL-4 specific sandwich ELISA with the purified 11B11 antibody (Cat. No. 554434) as a capture antibody and the biotinylated BVD6-24G2 (Cat. No. 554390) as the detection antibody. To obtain linear standard curves, doubling dilutions of this mouse IL-4 standard from ~2,000 to 15 pg/mL should be included in each ELISA plate. For assay of mouse IL-4 in complex fluids such as serum or plasma, the BD OptEIA™ Mouse IL-4 ELISA Set is recommended (Cat. No. 555198).

- Interleukin-4 (IL-4) is a species-specific cytokine which promotes the proliferation, differentiation and cell-surface protein modulation of B lymphocytes. IL-4 is responsible for activities previously assigned to BCGF, BCDF, BSF-2 and TCGF-2. Mouse IL-4 is a 14 kD protein containing 120 amino acid residues.
