B7-33 99% Pure Peptide

What is B7-33 99% Pure Peptide?

Xi'an Faithful BioTech Co., Ltd. specializes in biotech raw materials. We supply high-quality products worldwide with reliable service. B7-33 99% Pure Peptide is a high-purity, synthetically produced single-chain peptide, a classic human relaxin-2 mimic peptide. It boasts 99% high-performance liquid chromatography (HPLC) purity, is a dry white powder, and possesses stable physicochemical properties and excellent biological activity, making it a core research raw material in the life sciences. This peptide consists of 27 amino acids with a well-defined and stable amino acid sequence and molecular structure. It exhibits good water solubility in common research solvents such as pure water and PBS buffer, making it suitable for various in vitro cell experiments and in vivo animal model studies. Under proper low-temperature, light-protected, and sealed storage conditions, it maintains its activity for extended periods, demonstrating extremely high batch-to-batch stability. As a highly selective RXFP1 receptor agonist, B7-33 precisely targets and activates relaxin family peptide receptor 1, preferentially activating the ERK1/2 signaling pathway, circumventing the non-specific effects of natural relaxin. It can precisely regulate tissue remodeling and physiological processes related to inflammation and fibrosis, exhibiting research specificity far superior to natural relaxin.

B7-33 99% Pure Peptide Manufacturing Process

B7-33 99% Pure Peptide is produced using a standard solid-phase peptide synthesis process. Directed peptide chain splicing is performed based on precise amino acid sequences, followed by lysis and resin removal, multi-stage high-performance liquid chromatography purification, ultrafiltration desalting, and precision filtration, before being freeze-dried at low temperatures. Strict quality control screening is implemented throughout the process to effectively remove various impurities, ensuring a product purity of 99%, stable activity, and batch-to-batch uniformity, meeting the needs of various sophisticated scientific research experiments.

B7-33 is a completely linear single-chain polypeptide, without cyclic structures, disulfide bonds, or branched modifications. Its simple and stable structure distinguishes it from the natural double-chain complex structure of relaxin. The peptide chain has a free amino group at the N-terminus and a free carboxyl group at the C-terminus, with a straight-chain peptide structure linked by standard amide bonds. The peptide fragment simultaneously contains hydrophobic, polar, and basic amino acids, exhibiting both good water solubility and receptor binding activity. Its regular molecular conformation makes it resistant to structural denaturation, which is the core structural basis for its high targeting specificity and batch-to-batch stability.
