Product Information
| Description: | Disufide crosslinks of cystines in proteins can be reduced to cysteine residues by TCEP (tris-(2-carboxyethyl)phosphine). Unlike DTT (dithiothreitol), TCEP does not contain thiols and therefore usually does not need to be removed prior to thiol modification. |
| 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. |
