NF 157 is a purinergic receptor antagonist that potently inhibits P2Y11 receptor activity (IC50 = 463 nM). Displays selectivity for P2Y11 and P2X1 receptors over P2Y1, P2Y2, P2X2, P2X3, P2X4 and P2X7 receptors. Inhibits NAD+-induced activation of human granulocytes.
This product is supplied with a high degree of hydration and some residual NaCl, the amount of which are batch dependent. Please refer to the Certificate of Analysis to obtain the batch specific Net Product Content and the maximum solubility threshold to use in dilution calculations.

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
