IL-4重组蛋白|Recombinant Human IL4 / Interleukin-4 Protein(产品说明)
蛋白名称:Human IL4 / Interleukin-4 Protein
蛋白构建:A DNA sequence encoding the mature form of human IL4 isoform 1 (P05112-1) (His25-Ser153) was expressed and purified with an initial Met.
表达宿主:E. coli
蛋白纯度:≥ 95 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.
蛋白活性:Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is 0.05-0.25 ng/mL. The specific activity of recombinant human IL-4 is >10,000 IU/μg which is calibrated against the human IL-4 WHO International Standard (NIBSC code: 88/656).
蛋白内毒素:<10 EU per mg protein
预测N端:Met
蛋白分子量:The recombinant human IL4 consists of 130 amino acids and migrates with an apparent molecular mass of 15.1 kDa as predicted.
蛋白NP号:P05112-1
蛋白氨基酸序列:His25-Ser153
蛋白标签:Native
