Overview

Product Introduction

Necrostatin-5 is an inhibitor of necroptosis (non-apoptotic cell death pathway) by indirect inhibition of RIP1 kinase. Necroptosis is defined as alternative active cell death pathway: Death-Domain Receptor (DRs, e.g. Fas/TNFR) mediated and caspase-inhibitor insensitive with specific morphology (nuclear condensation, organelle swelling, loss of plasma membrane integrity). The necrostatins have been discovered to inhibit this pathway by inhibition of the death domain receptor-associated adaptor kinase RIP1. Three distinct mechanisms appear to be involved: T-loop dependent inhibition by necrostatin-1 partially T-loop independent inhibition by necrostatin-3 and indirect inhibition of RIP1 by necrostatin-5, since necrostatin-5 is a potent inhibitor of immunnoprecipitated RIP1, but does not inhibit recombinant RIP1.

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
