Description

Protein 60K, Chlamydia Trachomatis is a purified recombinant protein antigen derived from the 60 kDa cysteine-rich outer membrane protein of the *Chlamydia trachomatis* bacterium. This high-purity biological reagent is critical for the research, development, and quality control of diagnostic assays and vaccine candidates. It is an essential material for biotechnology, pharmaceutical, and in-vitro diagnostic (IVD) manufacturers focused on sexually transmitted infection (STI) and ocular trachoma diagnostics.

Application

• Diagnostic Assay Development: Key antigen for developing and calibrating ELISA, Western Blot, and rapid lateral flow tests for the detection of *Chlamydia trachomatis* antibodies.
• Vaccine Research: Used as a target immunogen in preclinical studies to evaluate immune response and efficacy of potential vaccine formulations.
• Quality Control (QC) Reagent: Serves as a positive control and reference standard in the manufacturing QC of commercial diagnostic kits to ensure lot-to-lot consistency and accuracy.
• Immunological Studies: Fundamental tool for investigating host-pathogen interactions, seroprevalence, and the immunopathology of chlamydial infections.
• Antibody Production & Purification: Used to immunize animals for polyclonal antibody production or as a ligand for affinity purification of specific antibodies.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch of Protein 60K, Chlamydia Trachomatis is characterized for identity, purity, and biological activity using advanced analytical techniques. Production follows strict guidelines to ensure reproducibility and low endotoxin levels suitable for immunological applications. Certificates of Analysis (COA) detailing purity, concentration, buffer composition, and specific test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. Avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature before opening to prevent condensation.
