The receptors CD96 and TIGIT are expressed on the surface of T and natural killer (NK) cells and recent studies suggest both play important inhibitory roles in immune function CD96 has been shown to modulate immune cell activity in mice with Cd96-/- mice displaying hypersensitive NK-cell responses to immune challenge and significant tumor resistance The counterbalance between the putative inhibitory CD96 and TIGIT receptors and the activating receptor CD226 offers unique strategies for immuno-oncology drug development

The EasySep™ Mouse MDSC (CD11b+Gr1+) Isolation Kit is designed to isolate CD11b+Gr1+ myeloid-derived suppressor cells (MDSCs) from single-cell suspensions of splenocytes or other tissues by negative selection. Unwanted cells are targeted for removal with biotinylated antibodies directed against non-MDSCs and streptavidin-coated magnetic particles (RapidSpheres™). Labeled cells are separated using an EasySep™ magnet without the use of columns. Desired cells are poured off into a new tube. Isolated cells are immediately available for downstream applications such as flow cytometry, cell sorting, and cell culture.

The Acetylcholinesterase Activity Assay Kit (Colorimetric) provides a simple quick and direct procedure for measuring Acetylcholinesterase levels in a variety of samples such as serum plasma tissues or cell lysates / cell extracts. This assay is based on the Ellman method in which thiocholine produced by Acetylcholinesterase reacts with DTNB 5 5A¢-dithiobis (2-nitrobenzoic acid) to form a colorimetric product (412 nm) proportional to the Acetylcholinesterase activity present. This kit does not require weighing or mixing of multiple reagents. The Acetylcholinesterase activity is measured without the use of a calibration curve. The Acetylcholinesterase Positive Control in the kit can be used to screen for Acetylcholinesterase inhibitors. The detection range 10-600 units/liter of Acetylcholinesterase activity.The detection time 5-10 minutesAcetylcholinesterase ( AChE) is a serine hydrolase found at neuromuscular junctions and cholinergic brain synapses. AChE hydrolyzes choline es
