IL-15RA Protein, Human, Recombinant (His & Avi), Biotinylated

Interleukin-15 receptor alpha (IL-15R alpha) is a high affinity IL-15 binding protein that is crucial for mediating IL-15 functions such as memory CD8 T cell proliferation and NK, NK/T cell, and intestinal intraepithelial lymphocyte development. IL-15RA Protein, Human, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 21.3 kDa and the accession number is Q13261-1.

产品描述

种属	Human
表达系统	HEK293
标签	C-His-Avi
蛋白编号	Q13261-1
别名	MGC104179, IL-15 R α, IL-15RA, IL-15 R alpha, IL-15RA/IL-15 R α/CD215, CD215
蛋白构建	Recombinant Biotinylated Human IL-15RA/IL-15 R alpha/CD215 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ile31-Thr205.[Accession \|Q13261-1]
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	The protein has a predicted MW of 21.3 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.

内毒素	Less than 1EU per μg by the LAL method.
缓冲液	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
复溶方法	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
存储	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
运输方式	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.
研究背景	Interleukin-15 receptor alpha (IL-15R alpha) is a high affinity IL-15 binding protein that is crucial for mediating IL-15 functions such as memory CD8 T cell proliferation and NK, NK/T cell, and intestinal intraepithelial lymphocyte development.
