ASO Positive Human Serum – Reliable Standard for Streptococcal Antibody Testing
Description:
ASO Positive Control Serum (Cat# D2070-C) is a high-quality human serum product containing elevated levels of Antistreptolysin O (ASO) antibodies. Specifically designed for use in clinical diagnostics and assay development, this control serum ensures consistent, accurate detection of antibodies associated with Streptococcus pyogenes infections. Manufactured under strict quality standards, it supports reliable performance in immunoassays, including ELISA, latex agglutination, turbidimetric, and nephelometric methods.
Key Features:
Verified ASO concentration ≥ 2,000 IU/mL – ideal for use as a positive control in serological assays
Human serum matrix – sourced and processed in the USA from screened human donors
Preservative-free – contains no additives, ensuring compatibility with a wide range of test platforms
Non-reactive for major viral markers – tested and confirmed negative for HIV 1/2, HBsAg, HCV, and STS using FDA-approved methods
Lot-specific characterization – includes total protein, albumin, cholesterol, triglycerides, pH, and bioburden
Use Cases:
Assay validation for ASO testing in diagnostic labs
Positive control for ELISA, latex agglutination, and nephelometric ASO assays
Quality assurance and lot-to-lot consistency monitoring
Research and development of streptococcal antibody detection methods
Clinical lab use in the diagnosis of rheumatic fever and post-streptococcal complications
