Product Name: sGnRH-A peptide
Batch to batch variation of the purity
sGnRH-A ([D-Arg⁶, Pro⁹]-LHRH) is a synthetic analog of gonadotropin-releasing hormone (GnRH). sGnRH-A can elevate the GH mRNA level and stimulate the GH secretion in common carp pituitary fragments in a dose-dependent manner. Compared to other GnRHs and its analogs, it shows a higher potency in increasing the GH mRNA level and GH release. In a time-course experiment, its function on GH secretion was observed after 6 h incubation, while its effect on the GH mRNA level was noted after 12 h treatment. Among mammalian GnRH, avian GnRH, and piscine GnRH, sGnRH and sGnRH-A showed the highest potency in increasing GH mRNA level and GH release, followed by cGnRH-II ([His⁵, Tyr⁸]-LHRH), and finally LHRH and LHRH-A ([D-Trp⁶, Pro⁹]-LHRH).
Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides.
Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.
Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.
Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.
In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
