Description

Troponin I Type 3 (Cardiac) is a highly specific biomarker protein critical for the diagnosis and monitoring of myocardial injury. Its primary value lies in its exceptional cardiac tissue specificity, making it a cornerstone for accurate clinical assessment of conditions like acute myocardial infarction. This product is essential for manufacturers of in-vitro diagnostic (IVD) kits, research institutions studying cardiovascular disease, and quality control laboratories developing reference materials.

Application

• Core Component in Cardiac Troponin I Immunoassays: Used as a key antigen in the development and calibration of ELISA, chemiluminescence, and lateral flow rapid tests for the detection of cardiac troponin I in human serum or plasma.
• Reference Standard Material: Serves as a primary or secondary standard for the quantification of cardiac troponin I in diagnostic kits, ensuring assay accuracy and reproducibility.
• Antibody Production & Characterization: Utilized as an immunogen to generate monoclonal or polyclonal antibodies with high specificity and affinity for cardiac troponin I.
• Clinical Research & Biomarker Studies: Employed in research models to investigate the release kinetics, degradation, and clinical significance of troponin I following cardiac events.
• Quality Control (QC) Reagents: Incorporated into positive control samples and proficiency testing panels to validate the performance of diagnostic testing systems.
• Point-of-Care Testing (POCT) Development: Integral to the design and optimization of rapid, decentralized diagnostic devices for cardiac injury.

Quality Control

Our Troponin I Type 3 (Cardiac) is produced and tested under a rigorous quality management system. Each batch is characterized for identity, purity, and biological activity using advanced analytical techniques to ensure it meets the exacting standards required for diagnostic and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, specificity, and functional data is provided with every shipment.

Storage

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