| Description : |
CD4 is a glycoprotein expressed on the surface of T helper cells, regulatory T cells, monocytes, macrophages, and dendritic cells. It was discovered in the late 1970s and was originally known as leu-3 and T4 (after the OKT4 monoclonal antibody that reacted with it) before being named CD4 in 1984. In humans, the CD4 protein is encoded by the CD4 gene. |

| Note : |
If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >10ug/ml. |
| Supplied : |
Lyophilized protein. |
| Purity : |
>95% by SDS-Page analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug). |
| Reconstitution : |
The lyophilized protein soluble in water and most aqueous buffers. The lyophilized powder should first be quick spun in vial, then reconstituted in water to a concentration of 0.1-1.0mg/ml. Allow to set at least 30 minutes at 4℃. If desired, can centrifuge for 1 minute at 1000 rpm to concentrate material in vial. |
| Biological Activity : |
Determined by its inhibitory effect of IL-8 production in human PBMC by human sTRAIL/Apo2L. 95% inhibition (100 ng/ml of s TRAIL/Apo2L) was reached using a concentration of 100 ng/ml of sTRAIL Receptor-1. |
| Storage : |
The lyophilized powder, though stable at room temperature for a few weeks, is best stored dessicated at -20℃. Reconstituted sTrail Receptor-1 should be stored in working aliquots at -20℃. Avoid Frequent Freeze-THAW Cycles. |
