Compound profile: B7-33 (Relaxin Analog)

B7-33 (Relaxin Analog) is a truncated single-chain analogue of the B-chain of human relaxin-2.

It also appears in the literature as relaxin analogue.

B7-33 is studied as a biased agonist relative to full-length relaxin. It is supplied as a lyophilised vial, which keeps it stable in transit and simple to log into inventory.

B7-33 (Relaxin Analog) is part of the EU Peptide Sciences and peptide science range, which lists 187 research compounds across 18 categories, each released against third-party analysis.

B7-33 (Relaxin Analog) research applications

B7-33 is a single-chain relaxin analogue built from the B-chain, designed to retain RXFP1 activation while dropping the complex two-chain structure. It shows biased signalling that favours anti-fibrotic pathways in the published work.

Published work on B7-33 (Relaxin Analog) sits in the research literature, always in vitro or in animal models. The main areas are:

• RXFP1 receptor binding and bias
• Fibrosis and collagen-deposition models
• Cardiac and renal tissue research
• Extracellular-matrix turnover assays
• Vascular remodelling
• G-protein-coupled receptor signalling

Cardiac and renal fibroblast cultures and rodent fibrosis models, with collagen deposition and MMP activity as endpoints.

Protocols covering fibrosis and collagen-deposition models tend to run B7-33 (Relaxin Analog) across a concentration range so that any relationship between exposure and readout can be described rather than assumed.

Where cardiac and renal tissue research is the endpoint, B7-33 (Relaxin Analog) is applied to a model system that has already been characterised, so that the sequence is the only variable under test.

Reference data

Fields that are not listed for B7-33 (Relaxin Analog) are not stated on the batch record, rather than omitted for brevity.

Laboratory handling notes

Relaxin-family analogues can be sticky; low-bind labware and carrier protein at low concentration improve recovery.

Store the unopened vial frozen and shielded from light; the lyophilised powder tolerates long storage in that state.

Once in solution, hold at 2–8 °C and work from a single reconstituted vial rather than re-freezing it. The full routine is set out in the peptide storage guide.

Stock-concentration arithmetic for a 6mg vial of B7-33 (Relaxin Analog): dissolved in 1 mL of diluent it gives 6 mg/mL, in 2 mL it gives 3 mg/mL, and in 5 mL it gives 1.2 mg/mL. Fixing the diluent volume before the vial is opened means every experiment in a study starts from the same stock.

Choosing between B7-33 (Relaxin Analog) and alternatives

Native relaxin has two chains joined by disulfide bridges, so a single-chain analogue like B7-33 is easier to make and gives more consistent batches; in the growth-axis group, sermorelin is the counterpart hormone analogue.

B7-33 (Relaxin Analog) is catalogued under peptides for healing. Researchers working in the same area also look at ara-290, bpc 157 and bpc-157/tb-500/kpv/ghk-cu blend. The whole peptide sciences range is listed under peptide sciences peptides and research peptides for sale.

Analytical verification

Independent testing sits between production and release. Identity, purity and mass are verified analytically, and the matching certificate of analysis is issued for the batch you are sent.

Labelling records compound, quantity and batch so that a result can always be traced to the material that produced it. Request a certificate at support@eupeptidesciences.com, and see how to read a peptide certificate of analysis for what to check on it.

Common questions from laboratories

What is biased agonism in this context?

It means the analogue activates some downstream pathways of RXFP1 more strongly than others, which is why it is used to separate anti-fibrotic from vasodilatory signalling.

Why use a single-chain analogue?

Native relaxin has two chains joined by disulfide bridges, which is difficult to make. A single-chain design is more consistent from batch to batch.

Is B7-33 (Relaxin Analog) for human use?

No. B7-33 (Relaxin Analog) is supplied strictly as a research chemical for laboratory work. It is not a medicine, not a supplement and must not be administered to humans or animals.

How should B7-33 (Relaxin Analog) be stored?

Store the unopened vial frozen and shielded from light; the lyophilised powder tolerates long storage in that state. Once in solution, hold at 2–8 °C and work from a single reconstituted vial rather than re-freezing it.

What is the minimum order and how long does delivery take?

The minimum order value is $100. Standard delivery takes 7–14 business days and express 3–7 business days, with rates shown at checkout. Orders of $250 or more ship express free, in discreet packaging with tracking.
