Protein dotMETRIC

For rapid estimation of protein concentration

The Protein dotMETRIC™ kit, from G-Biosciences, St Louis, is a 1-µL protein assay for the rapid estimation of protein concentration in cellular fractions, tissue, and cell lysates and chromatography purification fractions. The assay is compatible with sample-loading buffers and is ideal for confirming the amount of protein loaded on polyacrylamide gels. It is unaffected by the presence of common laboratory agents such as reducing agents, chelating agents, detergents, amines, sugars, chaotropes, and salts. Kits are supplied with an optional spot application device for increased reproducibility and test reliability. The spot application device allows application of samples using fixed-volume capillary tips and simplifies the task of applying the protein solution.

DNA Extraction Kits

For use with the PapilloCheck HPV test

Greiner Bio-One, Frickenhausen, Germany, launches two variants of a specially adapted DNA extraction kit for its cervical (cervix uteri) cancer test system, PapilloCheck. By expanding the product portfolio for the test system, the company now offers a simple and rapid complete solution for detection of human papilloma viruses. The two DNA Extraction Kits, certified as CE-IVD (in vitro diagnostics) suitable for isolating human and viral DNA, are specially developed for extraction of the DNA from uterine cervix smears for subsequent analysis with PapilloCheck. Depending on the sample frequency or volume, two different extraction kit processing methods can be applied: either single-column processing using centrifugation or processing eight columns applying a vacuum system.

BD ProbeTec Amplified DNA Assays

Screen for chlamydia and gonorrhea

BD Diagnostics, Durham, NC, has received FDA clearance to utilize its BD ProbeTec™ Chlamydia trachomatis Qx and Neisseria gonorrhoeae QX amplified DNA assays, allowing labs to screen for chlamydia and gonorrhea using liquid-based cytology (LBC) samples collected during routine cervical cancer screening. Labs can then run the assays on the BD Viper™ system. The remaining specimen can be forwarded to the cytology lab for LBC slide preparation and testing.
