分子别名 (Synonym)
CLMF; CLMF2; IL-12A; IL-12B; IL12; IL12 p70; IMD28; IMD29; NFSK; NKSF1; NKSF2; P35; IL-12 subunit p35; IL12A; interleukin 12
来源/表达系统 (Source)
Recombinant Human IL-12 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus of IL-12A.It contains Ile23-Ser328 (IL-12B) & Arg23-Ser219 (IL-12A) [Accession | P29460(IL-12B)&P29459(IL-12A)].
分子量
The protein has a predicted MW of 34.7 kDa(IL-12B) & 25.5 kDa(IL-12A). Due to glycosylation, the protein migrates to 40-45 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 1 EU per μg by the LAL method.
纯度 (Purity)
> 95% as determined by Bis-Tris PAGE
> 90% as determined by HPLC
制剂 (Formulation)
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
重构方法 (Reconstitution)
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
存储 (Storage)
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
