PubMed PubMed Product Detail This gene encodes four products of the tachykinin peptide hormone family, substance P and neurokinin A, as well as the related peptides, neuropeptide K and neuropeptide gamma. These hormones are thought to function as neurotransmitters which interact with nerve receptors and smooth muscle cells. They are known to induce behavioral responses and function as vasodilators and secretagogues. Multiple transcript variants encoding different isoforms have been found for this gene.

Function:
Tachykinins are active peptides which excite neurons, evoke behavioral responses, are potent vasodilators and secretagogues, and contract (directly or indirectly) many smooth muscles.
Subcellular Location:
Secreted.
Similarity:
Belongs to the tachykinin family.

P物质(Substance P)是脑组织及消化道中发现的一种神经递质肽。由130个氨基酸残基组成,胃肠道中肌肉收缩的有力促进剂,亦为强血管扩张剂。
SP是一种脑肠肽,亦是最早发现的一种神经肽,属于速激肽家族成员,它广泛分布于中枢及外周神经系统,作为一种神经递质或调质参与疼痛、免疫、Cardiovascular等多种生理功能的调节。SP与其它的递质或调质类似,能作用于多种类型的受体,速激肽家族有NK1、NK2、NK3三种受体,都能与SP结合,其中NK1与SP的结合能力最强而被称为SP受体。Product Picture Paraformaldehyde-fixed, paraffin embedded (rat adrenal gland); Antigen retrieval by boiling in sodium citrate buffer (pH6.0) for 15min; Block endogenous peroxidase by 3% hydrogen peroxide for 20 minutes; Blocking buffer (normal goat serum) at 37°C for 30min; Antibody incubation with ( Substance P) Polyclonal Antibody, Unconjugated (SL0065R) at 1:200 overnight at 4°C, followed by operating according to SP Kit(Rabbit) (sp-0023) instructionsand DAB staining.U-2OS cell; 4% Paraformaldehyde-fixed; Triton X-100 at room temperature for 20 min; Blocking buffer (normal goat serum, C-0005) at 37°C for 20 min; Antibody incubation with (Substance P) polyclonal Antibody, Unconjugated (SL0065R) 1:100, 90 minutes at 37°C; followed by a conjugated Goat Anti-Rabbit IgG antibody at 37°C for 90 minutes, DAPI (blue, C02-04002) was used to stain the cell nuclei.Blank control: Mouse brain cells (blue).
Primary Antibody:Rabbit Anti- Substance P antibody(SL0065R), Dilution: 1μg in 100 μL 1X PBS containing 0.5% BSA;
Isotype Control Antibody: Rabbit IgG(orange) ,used under the same conditions );
Secondary Antibody: Goat anti-rabbit IgG-PE(white blue), Dilution: 1:200 in 1 X PBS containing 0.5% BSA.
Protocol
The cells were fixed with 2% paraformaldehyde (10 min). Primary antibody (SL0065R, 1μg /1x10^6 cells) were incubated for 30 min on the ice, followed by 1 X PBS containing 0.5% BSA + 1 0% goat serum (15 min) to block non-specific protein-protein interactions. Then the Goat Anti-rabbit IgG/PE antibody was added into the blocking buffer mentioned above to react with the primary antibody at 1/200 dilution for 30 min on ice. Acquisition of 20,000 events was performed.
