Product Introduction

Bioactivity
Description
Substance P (Neurokinin P) (SP) is an undecapeptide (a peptide composed of a chain of 11 amino acid residues) member of the tachykinin neuropeptide family.
In vitro
The process involves the desensitization and resensitization of neuropeptide substance P (SP) through the neurokinin 1 receptor (NK1-R), which may relate to the endocytosis and recycling of NK1-R. Both SP and NK1-R are internalized into clathrin-immunoreactive vesicles and subsequently segregated into distinct compartments. Initially, SP remains intact on the cell surface and in early endosomes but gradually degrades in perinuclear vesicles. SP triggers the clathrin-dependent internalization of NK1-R. Within acidified endosomes, the SP/NK1-R complex disassociates, leading to the degradation of SP while NK1-R is recycled back to the cell surface. This mechanism of SP-induced NK1-R internalization is observed in transfected epithelial cells[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
