分子别名（Synonym）:IL1B

种属（Species）：Rat

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile 40mM Tris, 0.15 M NaCl, pH 7.8

分子量（Molecule Mass）：The mature form of recombinant rat IL1B comprises 153 amino acids and predicts a molecular mass of 17.4 kDa. The apparent molecular mass of the protein is approximately 35 kDa in SDS-PAGE under reducing conditions.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：1. Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells.

表达区间（Protein Construction）：A DNA sequence encoding the mature form of rat IL1B (Q63264-1) (Val 117-Ser 268) was expressed and purified.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
