Human Interleukin-3 Recombinant (CHO cell)
Categories: CytokinesRecombinant Human Cytokines$160.00 – $3,500.00
Description
Accession
P08700
Source
Optimized DNA sequence encoding Human Interleukin-3 mature chain was expressed in CHO cells.
Molecular weight
Native human Interleukin-3 is generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 15kDa. Recombinant IL-3 is a protein consisting of 133 amino acid residue subunits, and due to glycosylation migrates as an approximately 20kDa protein under reducing conditions in SDS-PAGE.
Purity
>97%, as determined by SDS-PAGE and HPLC
Biological Activity
The ED(50) was determined by the the ability to induce IFNg production in NK cells was foundless than0.1 ng/ml.

Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than.1 ng/µg(1EU/µg).
Presentation
Recombinant Interleukin-3 was lyophilized from a.2 μm filtered PBS solution pH7.0.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than.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 at° -° 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.
