Human Melanoma Inhibitory Activity Protein Recombinant
Category: Recombinant Human Cytokines$70.00 – $6,500.00
Description
Accession
Q16674
Source
Optimized DNA sequence encoding Human Interleukin-6 mature chain was expressed in Escherichia Coli
Molecular weight
Recombinant human IL-6, generated by the proteolytic removal of the signal peptide and propeptide, is a disulfide-linked homodimeric protein consisting of two amino acid residue subunits. The molecule has a calculated molecular mass of approximately kDa. rhIL-6 migrates as an approximately kDa protein under non-reducing conditions and as a - kDa protein under reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The ED(50) was determined by the dose-dependent stimulation of the proliferation of monkeyMBr-5 cells was found to be in the range of.0-40.0 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
Interleukin-6 was lyophilized from a 0.2 μm filtered solution in.5% glycine,.5% sucrose,.01% Tween80, mM Glutamic acid, 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.
Usage
