Speract Peptide
€103.00
In stock
SKU
350390
Protein Family: Hormones
Pathway and Disease: Cell Motility, Signaling molecules and Interaction
Alternate Names: Sperm-activating peptides; Speract-like; Speract
Accession No.: P11761
Description:
Speract peptide was first isolated from the jelly layer of a sea urchin (Strongylocentrotus purpuratus) eggs as a sperm-activating peptide. Speract peptide (at sub nanomolar range) stimulates sperm respiration and motility through intracellular alkalinization, transient elevations of cAMP, cGMP, and calcium levels in sperm cells, and transient activation and subsequent inactivation of the membrane form of guanylate cyclase. Speract peptide also acts as a chemoattractant.
Format:
Each vial contains 1 mg of lyophilized solid packaged under an inert gas and supplied as a trifluoroacetate salt.
MW: 891.94 g/mol
Sequence:
Sea Urchin: H-Gly-Phe-Asp-Leu-Asn-Gly-Gly-Gly-Val-Gly-OH or H-GFDLNGGGVG-OH
Composition:
C38H57N11O14
Purity:
> 95% by HPLC
Solubility:
Distilled water for a solution up to 2 mg/ml, otherwise we recommend using acetonitrile.
Storage:
Store at -20°C. The product is hygroscopic and must be protected from light. Product is guaranteed one year from the date of shipment. Following reconstitution, aliquot and store at -20°C.
