- Blood vessel relaxation
- Organ fibrosis research
What is B7-33?
Simplified relaxin-2 retaining anti-fibrotic and vasodilatory effects.
Listed vial contents: 6mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
What mechanisms are being studied?
B7-33 is a simplified single-chain analog of relaxin-2 that retains anti-fibrotic and vasodilatory properties. It activates RXFP1 to reduce collagen deposition, inhibit myofibroblast differentiation, and promote extracellular matrix remodeling.
What are the research questions?
- Organ fibrosis: Anti-fibrotic effects studied in cardiac, pulmonary, renal, and hepatic fibrosis models.
- Heart failure: Vasodilation and anti-fibrotic effects relevant to heart failure with preserved ejection fraction.
- Vascular function: Relaxin-mediated vasodilation improves blood flow and reduces vascular stiffness.
What does the published work describe?
Hossain MA et al. — B7-33 retains RXFP1 activation with anti-fibrotic and vasodilatory effects of native relaxin-2. Preclinical models show reduced cardiac and renal fibrosis.
What are the limits of this evidence?
The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is B7-33 handled in the lab?
For B7-33, record the product code B733, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
Choose a solvent for B7-33 from the documented sequence or chemical identity, salt form and assay requirements. Test a small portion first and record pH, solvent composition and clarity. Do not assume one diluent works for every research material; include a solvent-only control and establish compatibility before using the stock in an assay.
For B7-33, calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; no usable molecular weight is established by the blank catalog field. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
Use the documented storage conditions for the supplied B7-33 form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A B7-33 laboratory protocol should record identity, product code B733, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Research Use Only. Not for human consumption, therapeutic, veterinary or any in-vivo use.

Quality & Verification
B7-33 has a catalog purity specification of ≥98%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
Frequently Asked Questions
What is B7-33?
B7-33 is listed for specialty laboratory research. Catalog vial contents are 6mg; select the required strength before ordering. This material is supplied for Research Use Only, not as a medicine or a product for human or veterinary use.
What strengths of B7-33 are available?
The catalog lists 6mg. These labels describe vial contents, not administration doses. Select the required strength for current pricing and availability; match analysis records to that exact strength and lot.
How should I interpret B7-33 purity results?
B7-33 has a catalog purity specification of ≥98%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements.

How do I choose a laboratory solvent for B7-33?
Choose a solvent for B7-33 from the documented sequence or chemical identity, salt form and assay requirements. Test a small portion first and record pH, solvent composition and clarity. Do not assume one diluent works for every research material; include a solvent-only control and establish compatibility before using the stock in an assay.
How do I calculate a B7-33 stock concentration?
For B7-33, calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; no usable molecular weight is established by the blank catalog field. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
How should B7-33 be stored after preparation?
Use the documented storage conditions for the supplied B7-33 form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
What should a B7-33 lab protocol document?
A B7-33 laboratory protocol should record identity, product code B733, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Does Fmoc or Boc synthesis explain this B7-33 product?
Fmoc and Boc are peptide protecting-group strategies, not proof of how this B7-33 lot was made. For sequence-defined peptides, synthesis review can examine deletion products, incomplete deprotection and modifications using the method and matching analytical evidence. A single chromatographic peak does not by itself establish sequence.
Is B7-33 for human use?
No. B7-33 is strictly Research Use Only. It is not intended for human or veterinary use, diagnosis or treatment. Laboratory handling guidance is not an administration protocol.
Research Use Only. This product is intended for licensed laboratory research and is not for human or veterinary use.
