Technical Data
Substance P (NKA, NKNA, TAC2)
The COOH terminal end of substance P, a short polypeptide neurotransmitter that regulates the excitability of dorsal horn nociceptive neurons. It is known to have a role in several physiologic activities such as pain transmission, the vomiting reflex, salivary secretion and smooth muscle contraction.

Suitable for use in Immunofluorescence and Immunohistochemistry (frozen and paraffin). Other applications not tested.

Recommended Dilution:
Immunohistochemistry (frozen): 1:100-1:200
Immunohistochemistry (paraffin): 1:100-1:200
Optimal dilutions to be determined by the researcher.

NS1/1-Ag 4-1 myeloma cells with spleen cells from Wistar rat.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Substance P (BSA).
Supplied as a liquid, 0.09% thiomersal.
Recognizes the COOH terminal end of substance P. 5% reactivity is observed with eledoisin. It does not react with Leu or Met-enkephalin, somatostatin or beta-endorphin.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
