PACAP (1-38), human, ovine, rat ( Pituitary Adenylate Cyclase Activating Polypeptide 38 )

Catalog No. M29754 CAS No. 137061-48-4

PACAP (1-38), human, ovine, rat TFA is a neuropeptide with 38 amino acid residues. PACAP (1-38) binds to PACAP type I receptor, PACAP type II receptor VIP1, and PACAP type II receptor VIP2 with IC50s of 4 nM, 2 nM, and 1 nM, respectively. IC50: 4 nM (PACAP type I receptor), 2 nM (PACAP type II receptor VIP1), and 1 nM (PACAP type II receptor VIP2).

Biological Information

  • Product Name
    PACAP (1-38), human, ovine, rat
  • Note
    Research use only, not for human use.
  • Brief Description
    PACAP (1-38), human, ovine, rat TFA is a neuropeptide with 38 amino acid residues. PACAP (1-38) binds to PACAP type I receptor, PACAP type II receptor VIP1, and PACAP type II receptor VIP2 with IC50s of 4 nM, 2 nM, and 1 nM, respectively. IC50: 4 nM (PACAP type I receptor), 2 nM (PACAP type II receptor VIP1), and 1 nM (PACAP type II receptor VIP2).
  • Description
    PACAP (1-38), human, ovine, rat TFA is a neuropeptide with 38 amino acid residues. PACAP (1-38) binds to PACAP type I receptor, PACAP type II receptor VIP1, and PACAP type II receptor VIP2 with IC50s of 4 nM, 2 nM, and 1 nM, respectively. IC50: 4 nM (PACAP type I receptor), 2 nM (PACAP type II receptor VIP1), and 1 nM (PACAP type II receptor VIP2).(In Vitro):PACAP (1-38), human, ovine, rat is a fragment of pituitary adenylate cyclase activating polypeptide. PACAP (1-38) shows high affinity for PACAP specific (PAC1) receptor in membranes from various tissues including the endocrine pancreas. In vitro, PACAP (1-38) relaxes guinea-pig and rabbit tracheal smooth muscle precontracted by histamine and by acetylcholine. PACAP (1-38) also increases adenosine 3':5'-cyclic monophosphate (cyclic AMP) in tracheal smooth muscle, providing a possible mechanism for the relaxant effect of PACAP (1-38).(In Vivo):PACAP (1-38) alone in sham animals does not result in changes in any of the retinal layers. PACAP (1-38) dissolved in solutio ophthalmica cum benzalkonio leads to significant protection in the retina in bilateral common carotid artery occlusion (BCCAO)-lesioned retinas; retinas treated with PACAP (1-38) eye drops have preserved structure compared to control retinas. OLM-ILM (outer limiting membrane-inner limiting membrane) distance is reduced by 49.7% (p<0.001) in BCCAO retinas compared to sham controls, but it is only 40.6% (p<0.001) in the eyes treated with PACAP (1-38) eye drops. A protection to a similar degree is found in the inner nuclear layer (INL) (BCCAO: 38.5%, PACAP (1-38): 30.5%; p<0.001), and inner plexiform layer (IPL) (BCCAO: 64.8%, PACAP (1-38): 38.2%; p<0.05), while no statistically significant attenuation of the damage is observed in the outer nuclear layer (ONL) (BCCAO: 36.5%, PACAP (1-38): 37.7%) or outer plexiform layer (OPL) (BCCAO: 53.0%, PACAP (1-38): 48.2%). The number of cells in the ganglion cell layer (GCL) is significantly decreased after BCCAO by 52.4% (p<0.05) and is significantly ameliorated by PACAP (1-38) eye drops (decreased by 25.9%; p<0.05).
