Technical Data
Interleukin 1 alpha, Recombinant, Rat (IL-1a, Hematopoietin-1, Lymphocyte-activating Factor, LAF, Endogenous Pyrogen, Leukocyte Endogenous Mediator, LEM, Mononuclear Cell Factor, MCF)
Molecular Biology Storage: -20CShipping: Blue Ice
Recombinant corresponding to rat Interleukin 1 alpha expressed in E. coli.

Molecular Weight:

Endotoxin: 0.1 ng/ug

ED50 range =0.001-0.005 ng/ml, determined by the dose dependent proliferation of mouse D10S cells. The optimal concentration for individual application should be determined by an initial dose response assay.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
Source: E. coli
Purity: ~95% (SDS-PAGE)
Concentration: Not determined
Form: Supplied as a lyophilized powder. BSA free. Reconstitute with sterile dH2O to 0.1-1mg/ml.
