Active Recombinant Human IL2, His tagged

• Cat.No.: IL2-501H
• Product Overview: Recombinant Human Interleukin-2/IL-2 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Pro22-Thr153) of Human IL-2 fused with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: Human Cells
• Tag: His
• Protein Length: 22-153 a.a.
• Description: Recombinant Human Interleukin-2 is a highly purified protein with a molecular weight of approximately 15,300 Daltons. The chemical name is des-alanyl-1, serine-125 Human Interleukin-2. It is produced by recombinant DNA technology using a genetically engineered E. coli strain containing an analog of the human interleukin-2 gene. Genetic engineering techniques were used to modify the Human IL-2 gene, and the resulting expression clone encodes a modified Human IL-2. This recombinant form differs from native Interleukin-2 in following ways: 1) it is not glycosylated; 2) the molecule has no N-terminal alanine; 3) the molecule has serine substituted for cysteine at amino acid position 125; 4) the aggregation state of molecule is likely to be different from that of native IL-2.
• Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
• Bio-activity: >1.0 x 10^7 U/mg
• Endotoxin: Less than 0.1 EU/μg.
• Purity: Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.
• Storage: Lyophilized protein should be stored at< -20°c,="" though="" stable="" at="" room="" temperature="" for="" 3="">Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at< -20°c="" for="" 5="">
• Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in 1X PBS.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
