Description
Recombinant Mouse Interleukin-4 is produced by our Mammalian expression system and the target gene encoding His21-Ser140 is expressed with a 6His tag at the C-terminus.
Alias
Interleukin-4; IL-4; IL4; B-cell IgG differentiation factor; B-cell growth factor 1; B-cell stimulatory factor 1; BSF-1; IGG1 induction factor; Lymphocyte stimulatory factor 1
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured in a cell proliferation assay using CTLL‑2 mouse cytotoxic T cellsThe ED50 for this effect is less than 2 ng/ml.
Formulation
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
Storage
