Immunohistochemical analysis of Neurokinin-1 expression in FFPE mouse islets.

Cat#RPA25103 was used as primary antibody, dilution 1:500.


Immunohistochemical analysis of Neurokinin-1 receptor expression in mouse lung tissue.

Cat#RPA25103 was used as primary antibody, dilution 1:500.

Polyclonal neurokinin-1 receptor antibody was produced from sera of rabbits  immunized with synthetic protein containing neurokinin-1 receptor  antigenic determinants. 
Species reactivity:

Serum IgG fraction was purified by Protein G affinity chromatography.

Lyophilized from sterile filtered PBS solution at a concentration of 1mg/ml.
A quick spin of the vial followed by reconstitution in distilled water. This solution can then be diluted into other buffers
The lyophilized antibody is stable for at least 1 year  from date of receipt at -20° C.
Upon reconstitution, this antibody can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months without detectable loss of activity.

Avoid repeated freeze/thaw cycles.

NK-1, an 11-amino-acid neuropeptide, is released from enteric nerves, sensory neurons, and inflammatory cells of the lamina propria during intestinal inflammation. Conversely, Substance-P activates nerves, epithelial cells, and a variety of immune and inflammatory cells, leading to the release of cytokines, chemokines, and other neuropeptides that modulate diarrhea, inflammation, and motility changes associated with several intestinal disease states, including IBD . Substance-P mediates the development and progression of intestinal inflammation by binding to its high-affinity receptor, the neurokinin 1 receptor (NK-1R). Our laboratory has shown that SP-NK-1R interactions play a dual role in the development and maintenance of colonic inflammation. Thus NK-1R- deficient mice are protected during the acute phase of colitis yet exhibit an enhanced inflammatory response during chronic colitis. Neurokinin-1 was also recently shown to rescue colonic cells from apoptosis, preserving colonic tissue integrity in a murine DSS colitis model
