Reagents

C-reactive protein assay

The Piccolo MetLyte Plus CRP Reagent Disc, used with the Piccolo xpress chemistry analyzer, is intended to be used for the in vitro quantitative determination of C-reactive protein, chloride, creatine kinase, creatinine, glucose, potassium, sodium, total carbon dioxide and blood urea nitrogen (BUN) in heparinized whole blood, heparinized plasma, or serum in a clinical laboratory setting. ­Users can conduct on-site chemistry analysis in less than 12 minutes for conditions such as infections, inflammatory diseases, tissue injury, and some neoplastic processes. CRP is widely used as an indicator of inflammation or infection, including rheumatoid arthritis, although the test has utility in the detection and treatment of other afflictions as well.

Two-part liquid homocysteine reagent

Elevated homocysteine is now widely accepted as an important risk factor for cardiovascular disease. This Homocysteine Assay, a two-part liquid stable reagent for automated clinical chemistry analyzers, incorporates an enzyme-cycling sequence that offers an 18-month shelf-life, 30-day on-board stability, and extended calibration stability. Calibrator value is standardized to NIST SRM 1955, and the assay shows excellent correlation with immunoassay and HPLC methods.

New application

A new direct HbA1c reagent application for the Vital Diagnostics Envoy500 Analyzer is available. The unique single-channel immunoturbidimetric assay is fully automated, requires no manual sample preparation, no separate total hemoglobin measurement, and no additional calculations. Non-specific binding of total hemoglobin, both glycated and non-glycated, to latex particles is employed in the first reaction. Specific antibodies used in the second-reaction result in agglutination of only HbA1c-bound latex particles. The absorbance of the agglutination is measured at 600 nm to 660 nm, and the HbA1c concentration is determined using calibrators with known HbA1c values.

Variety of reagents

A variety of reagents for diagnosis and monitoring of prostate cancer using immunohistochemical staining procedures include prediluted and concentrated antibodies for PSA, p63, and P504S (Racemase) is available. Also available is the PIN-4 multiplex stain, which permits simultaneous localization of three antigens (p63, high molecular-weight cytokeratin, and P504S) on the same slide.  This two-color stain provides rapid differentiation of high-grade prostatic intraepithelial neoplasia (PIN) from invasive carcinoma and benign lesions.
