IL4 Recombinant Human Protein, Invitrogen™ Sino Biological™ 
This recombinant protein was expressed from a DNA sequence encoding the mature form of human IL4 isoform 1 (P05112-1) (His 25-Ser 153) retaining the initial Met
Manufacturer: Invitrogen LS11846HNAE50
Description
Interleukin 4 (IL-4), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure, and performing cell based assays. It can also be used as an immunogen, as a protein standard, or in other research applications.- Activity: Measured in a cell proliferation assay using TF1 human erythroleukemic cells (Kitamura, T. et al.,1989, J. Cell Physiol. 140:323.); the EC50 for this effect is typically 0.1-0.3ng/mL
- Formulation: Lyophilized in 140mM NaCl, 2.7mM KCl, 10mM Na2HPO4, 1.8mM KH2PO4, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80
- Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible
This protein is manufactured by Sino Biological Inc.
