Non-transgenic plants (Nicotiana benthamiana) expression system
Purification:
Sequential chromatography (FPLC)
Purity:
> 97% by SDS-PAGE
Endotoxin Level:
< 0.04 EU/ug protein
Activity:
The specific activity is determined by the dose-dependent stimulation of the proliferation of human TF-1 cells (human erytroleukemic indicator cell line). ED50≤ 1 ng/mL.
Quality Control Testing:
0.3 ug/lane in 15% SDS-PAGE Stained with Coomassie Blue
It has a predicted molecular mass of 22.2 kDa, however as result of potential glycosylation; the recombinant protein could migrate with an apparent molecular mass of 23-24 kDa in SDS-PAGE gel.
Storage Buffer:
Lyophilized from 10 mM Phosphate Potasium buffer, 50 mM NaCl, pH 7. 4
Storage Instruction:
Store at -20°C on dry atmosphere. After reconstitution with sterilized water containing 0.1% HSA or BSA to a concentration of 50 ng/ul, store at -20°C. Aliquot to avoid repeated freezing and thawing.
Note:
Result of activity analysis
Applications
Western Blot (Recombinant protein)
Western Blot analysis of 300 ng recombinant IL6 prottein.
This gene encodes a cytokine that functions in inflammation and the maturation of B cells. The protein is primarily produced at sites of acute and chronic inflammation, where it is secreted into the serum and induces a transcriptional inflammatory response through interleukin 6 receptor, alpha. The functioning of this gene is implicated in a wide variety of inflammation-associated disease states, including suspectibility to diabetes mellitus and systemic juvenile rheumatoid arthritis.
