Description

Hcg-Beta (Gly(88,90))82-101 is a synthetic peptide fragment derived from the β-subunit of human chorionic gonadotropin (hCG). This high-purity reference standard is critical for research and development in the life sciences, particularly for immunoassay calibration and specificity studies. It is primarily utilized by pharmaceutical R&D teams, diagnostic kit manufacturers, and academic research institutions focused on reproductive endocrinology and biomarker discovery. The compound is supplied with full analytical characterization to ensure reliable and reproducible results.

Application

• Immunoassay Development & Calibration: Serves as a precise reference standard for the development and calibration of diagnostic immunoassays targeting hCG.
• Antibody Specificity Testing: Used to evaluate the binding affinity and specificity of monoclonal and polyclonal antibodies raised against the hCG β-subunit.
• Pharmaceutical Research: Employed in preclinical studies related to fertility treatments, cancer research (as certain cancers produce hCG), and hormone-related disorders.
• Quality Control in Diagnostics: Acts as a critical quality control material for lot-to-lot consistency testing in commercial diagnostic test manufacturing.
• Academic & Biomedical Research: Facilitates fundamental research into the structure, function, and metabolic pathways of gonadotropin hormones.
• Biomarker Studies: Used in proteomics and biomarker discovery projects to understand hCG variants and their clinical significance.

Quality Control

Every batch of Hcg-Beta (Gly(88,90))82-101 is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality system is designed to meet the exacting standards required for research and diagnostic applications. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), peptide content, amino acid analysis, and mass spectrometry data is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a dry environment before opening to minimize moisture uptake. For long-term storage, consider storing under an inert atmosphere.
