Stamford, Lincolnshire -- (SBWire) -- 01/17/2012 --2B Scientific, a leading UK distributor of life science reagents announce a new tool for scientists working in the field of apoptosis, pSIVA – Polarity Sensitive Indicator of Viability and Apoptosis from IMGENEX Corporation. This new tool for apoptosis, flow cytometry and microscopy is the first reversible probe for detecting phosphatidlyserine (PS) on plasma membranes. The reversible nature of the probe differentiates it from previous products which are all characterized by irreversible binding. This new capability opens up types of analysis previously unavailable to scientists.

pSIVA is an annexin based, polarity sensitive probe for the spatiotemporal or kinetic analysis of apoptosis and other forms of cell death. The new probes reversible binding enables researchers, for the first time, to detect transient PS exposure which is associated with both normal physiological processes as well as reversible or rescuable apoptosis cell death events.

Passing comment, James Bernard CEO of 2B Scientific said, “We are delighted to announce the availability of another novel and innovative product from IMGENEX that will provide our customers with an analytical advantage over traditional apoptosis probes, pSIVA novel binding capabilities will allow scientists to analyse and quantify new aspects of apoptosis previously unattainable to researchers.”
