生物活性

Biotin-Substance P is the biotin tagged Substance P. Substance P (Neurokinin P) is a neuropeptide, acting as a neurotransmitter and as a neuromodulator in the CNS. The endogenous receptor for substance P is neurokinin 1 receptor (NK1-receptor, NK1R)[1].

体外研究
(In Vitro)

The neuropeptide substance P (SP) that are mediated by the neurokinin 1 receptor (NK1-R) desensitize and resensitize, which may be associated with NK1-R endocytosis and recycling. SP and the NK1-R are internalized into the same clathrin immunoreactive vesicles, and then sorted into different compartments. SP is intact at the cell surface and in early endosomes, but slowly degraded in perinuclear vesicles. SP induces clathrin-dependent internalization of the NK1-R. The SP/NK1-R complex dissociates in acidified endosomes. SP is degraded, whereas the NK1-R recycles to the cell surface. SP induces internalization of the NK1-R both in transfected epithelial cells[1].

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Calculations:
For best results, use ≥ 12-fold molar excess of biotin for a 10 mg/mL protein solution or ≥ 20-fold molar excess of biotin for a 2 mg/mL protein solution.
1.Calculate millimoles of biotin reagent to add to the reaction for a 20-fold molar excess:
mL protein × (mg protein/mL protein) × (mmoL protein/mg protein) × (20 mmoL protein/mmoL protein) = mmoL Biotin.
* 20 = Recommended molar fold excess of biotin for 2 mg/ml protein sample
2. Calculate microliters of 10 mM biotin reagent solution (prepared in Step B.3) to add to the reaction:
mmoL Biotin × (1000000 μL/L) × (L/ 10 mmoL) =μL Biotin
Biotin Labeling Reaction:
1. Dissolve 1-10 mg protein in 0.5-2.0 mL PBS according to the calculation made in Calculations.
2. Before use, prepare a 10 mM solution of the biotin reagent in an organic solvent such as DMSO.
3. Add the appropriate volume (μL) of 10 mM biotin reagent solution to the protein solution.
4. Incubate reaction on ice for two hours or at room temperature for 30 minutes.
5. To tests the labeled protein by ELISA or Western blot.

ATP-polyamine-biotin (APB) is incubated with PKA kinase and full-length protein substrate, myelin basic protein (MBP). Biotinylation was observed only in presence of kinase. In addition, MBP biotinylation was lost in the absence of ATP-polyamine-biotin, in presence of the kinase inhibitor staursporine or upon incubation with acid due to cleavage of phosphoramidate bond. Biotinylated kemptide product is observed only in the presence of APB cosubstrate[1].
