B7-33 (6mg)
B7-33 is a single-chain analogue derived from the B-chain of human H2 relaxin. It retains RXFP1 binding while being far simpler to synthesise than the two-chain parent hormone, so it appears in fibrosis and receptor-selectivity studies.

About B7-33 (6mg)
Two-chain relaxin is expensive and difficult to produce at scale. The practical appeal of B7-33 is that it reproduces the receptor interaction from a single synthesised chain.
Like everything in the Peptides range, this vial is lyophilized, sealed, and accompanied by third-party purity documentation for its batch.
Research applications
B7-33 (6mg) appears in the following research contexts. These are descriptions of published laboratory work, not instructions for use:

Handling, reconstitution and storage
Store the sealed vial of lyophilized B7-33 at -20°C, protected from light. Allow it to reach room temperature before opening so that moisture does not condense onto the powder.
Reconstitute with bacteriostatic water directed down the inside wall of the vial rather than onto the cake, and swirl instead of shaking — mechanical agitation is the most common cause of degradation in peptide handling. Keep reconstituted solution at 2-8°C and validate its working life for your own assay conditions.
Frequently asked questions
- How is B7-33 (6mg) supplied and stored?
- It ships as a lyophilized powder in a sealed vial. Store the lyophilized product at -20°C protected from light; once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use it within the window your protocol validates.
- Is a certificate of analysis available?
- Yes. Every batch is independently tested by a US laboratory and verified to exceed 99% purity by HPLC/MS. Request the COA for your batch number and we will send the report.
- How long does delivery take?
- Orders dispatch within two business days. Delivery is free within the USA on orders over $200.
- Can B7-33 (6mg) be used in humans or animals?
- No. This product is sold strictly for research, laboratory and analytical purposes. Human and animal consumption is prohibited.
