Description

Cfp10 (71-85) CAS NO 646997-09-3 is a synthetic peptide fragment derived from the CFP-10 protein, a key antigen used in immunological research and diagnostic development. This high-purity peptide is critical for advancing studies in tuberculosis (TB) immunology and the development of sensitive diagnostic assays. It is primarily utilized by research institutions, diagnostic kit manufacturers, and pharmaceutical companies engaged in infectious disease research and vaccine development.

Application

• Tuberculosis (TB) Diagnostic Development: As a core antigen for ELISA, ELISPOT, and other immunoassays to detect immune responses to *Mycobacterium tuberculosis*.
• Immunological Research: Used in epitope mapping, T-cell stimulation studies, and investigating host-pathogen interactions in TB.
• Vaccine Research & Development: Serves as a reference standard or component in evaluating candidate TB vaccines.
• Quality Control & Standardization: Acts as a reference material for calibrating diagnostic tests and ensuring batch-to-batch consistency in kit production.
• Academic & Clinical Studies: Employed in research to understand latent TB infection, disease progression, and treatment efficacy.

Quality Control

Every batch of Cfp10 (71-85) is manufactured and analyzed under strict quality management systems. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with research-grade standards and precise sequence accuracy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and content is provided with each shipment.

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 desiccator before opening to prevent condensation and hydrolysis. For long-term storage, consider aliquoting to minimize freeze-thaw cycles.
