Product Information
| Description: | CD40 Ligand (CD40L/CD154/TRAP) is a type II transmembrane glycoprotein that belongs to the TNF superfamily. The CD40 ligand stimulates B-cell proliferation and secretion of all immunoglobulin isotypes in the presence of cytokines. Recombinant Human CD40 Ligand is produced by E.coli expression system and the target gene encoding Met113-Leu261 is expressed. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
