Bovine NPPB ELISA: A Key Diagnostic Tool for Cardiovascular Research
The Bovine Natriuretic Peptides B (NPPB) ELISA is a highly sensitive and specific immunoassay designed for the quantification of NPPB in bovine serum, plasma, and other biological fluids. Natriuretic peptides, including NPPB, play a critical role in cardiovascular physiology, regulating blood pressure, fluid balance, and cardiac function. This ELISA kit is an essential tool for veterinary research, clinical diagnostics, and animal health monitoring.
Key Features and Benefits
- High Sensitivity and Specificity: Detects low concentrations of NPPB with high accuracy.
- Quantitative Analysis: Provides precise measurement of NPPB in various bovine biological samples.
- Rapid and Reliable: Delivers results within 2-3 hours for efficient laboratory workflow.
- Ready-to-Use Kit Components: Includes all necessary reagents, buffers, and standards.
- Wide Dynamic Range: Covers a broad spectrum of NPPB concentrations.
- Validated for Veterinary Use: Ensures reliability in bovine health diagnostics.
Principle of the Assay
The NPPB ELISA utilizes a sandwich enzyme-linked immunosorbent assay (ELISA) format:
- Capture Antibody: Coated onto microplate wells to bind NPPB in the sample.
- Detection Antibody: Recognizes and binds to the captured NPPB.
- Enzyme-Conjugated Secondary Antibody: Reacts with the detection antibody.
- Substrate Reaction: Produces a colorimetric signal proportional to NPPB levels.
- Absorbance Measurement: Quantified using a microplate reader at 450 nm.
Applications
- Cardiovascular Research: Studies heart function and natriuretic peptide pathways in bovine species.
- Veterinary Diagnostics: Detects cardiac-related conditions in cattle.
- Endocrinology Studies: Investigates hormonal regulation of fluid balance and blood pressure.
- Livestock Health Monitoring: Tracks cardiac biomarkers for early disease detection.
- Comparative Biology Studies: Assesses natriuretic peptide evolution across species.
