Wiley RG, Kline IV RH, Vierck Jr CJ (2007) Anti-nociceptive effects of selectively destroying substance P receptor-expressing dorsal horn neurons using [Sar(9),Met(O(2))(11)]-substance P-saporin: Behavioral and anatomical analyses. Neuroscience 146:1333-1345. doi: 10.1016/j.neuroscience.2007.01.066
Summary: While lumbar injections of SP-SAP (Cat. #IT-07) produce specific lesions, use of this targeted conjugate in the forebrain has been problematic. The authors investigated the use of SSP-SAP (Cat. #IT-11), a conjugate of saporin with a stable analog of substance P. The greater stability of SSP-SAP resulted in increased potency as well as better specificity. SSP-SAP is shown to be a highly effective reagent for the removal of NK1 receptor-expressing neurons in the brain and spinal cord.
