PathHunter® Jurkat SIRPa Signaling Bioassay Kit

The PathHunter Jurkat SIRPa Signaling Bioassay Kit provides an easy-to-use cell based assay to measure drug potency and detect neutralizing antibodies. This bioassay asseses ligand (e.g. TGR5 Receptor Agonist) based on activation of SIRPa Checkpoint activity via detection of cAMP. The included cell line overexpresses ProLink-tagged SIRPa and EA-tagged . Activation of SIRPa stimulates the recruitment of and produces EFC signal. Bioassay kits are a convenient, ready-to-use format which contains all materials needed to run the assay, including single-use vials of cryopreserved cells, cell plating media, control agonist, detection reagent, and assay plates.

The following graph is an example of a typical dose-response curve for the SIRPα signaling bioassay generated using the protocol outlined in this manual. The data shows a potent, dose-dependent inhibition of the CD47-SIRPα signaling axis, when treated with the control anti-CD47 antibody. The plate was read on the EnVision® Multimode Plate Reader and data analysis done using GraphPad Prism.
See User Manual for Product Configuration Details. The purpose of the control ligand included in the Bioassay Kit is for verification of assay performance relative to the data shown in the Certificate of Analysis for that kit. This control ligand is not intended for use as a reference standard for validation studies and lot release applications. Typically, a reference medicinal product (RMP) that has been pre-defined by the customer as an internal reference standard is used for those applications. The RMP is not provided with the bioassay kit or supplied by Eurofins DiscoverX.
Short term (<24 h): Store at -80°C; Long term (>24 h): Store in vapor phase of liquid nitrogen.
