Description
Accession
Q12904
Source
Optimized DNA sequence encoding Human EMAP-II mature chain was expressed in Escherichia Coli.
Molecular weight
Native human EMAP-II, generated by the proteolytic removal by caspase-7 in response to apoptosis to produce EMAP-II, the molecule has a calculated molecular mass of approximately 18 kDa. Recombinant EMAP-II is a monomer protein consisting of 167 amino acid residue subunits,and migrates as an approximately 18 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The ED(50) was determined by apoptotic effect on MCF-7 cells using a concentration of-50 ng/ml.

Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant EMAP-II was lyophilized from a 0.2 μm filteredmM PB,130mM NaCl solution pH.5.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at2° -8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
