| 品名 |
Human Interleukin 15 / IL-15Rα Heterodimer (Human Cell-Expressed) |
||
| 规格 |
50 µg |
||
| 分子量 | 31 kDa predicted (12.8 kDa for IL-15 + 18.4 kDa for sIL-15Rα). Heterodimer exhibits multiple bands on reducing SDS-PAGE due to varying degrees of glycosylation; migrates to a single band at ~87 kDa, observed in Native-PAGE | ||
| 来源 |
Recombinant DNA expressed in Human Embryonic Kidney Cells (HEK293) |
||
| 纯度 |
Greater than 95% as determined by SDS-PAGE by a combination of ion exchange and size exclusion chromatography |
||
| 生物活性 |
Typically <0.5 ng/ml (15.6 pM), measured by its dose dependent stimulation of the proliferation of CTLL-2 cells |
||
| 缓冲液 |
Phosphate buffered saline (PBS) containing 0.1% bovine serum albumin (BSA) |
||
| 内毒素 |
< 1 EU/μg |
||
| 纯度 |
> 95% as determined by SDS-PAGE |
||
|
纯化方法 |
A combination of ion exchange and size exclusion chromatography |
||
| 贮存 |
For retention of full activity store at -70 ºC or below and avoid repeated freeze-thaw cycles |
