New Products: A Mass Spec-Based Thyroglobulin Test from Quest and More


Quest Diagnostics has introduced its Thyroglobulin Post-treatment Monitoring Test for monitoring recurrence of thyroid cancer following surgery.

The product is the first clinical test to use mass spectrometry to measure Tg, the company said, and is intended for use in samples where anti-Tg autoantibody production precludes use of conventional immunoassays.

Phenomenex this week released its new Yarra line of aqueous size exclusion chromatography columns for biomolecule analysis.

The columns come in three phases with 3-micron particles and are designed for separations of small to large proteins and peptides as well as biopharmaceuticals.

Enzo Life Sciences has released its new [pThr202/Tyr204]Erk ½ ELISA kit, which its says allows for detection of as little as 2.67 pg/ml of phosphorylated ERK1/2 and can process up to 40 samples in duplicate in three hours.

Everest Biotech is offering custom goat polyclonal antibodies for $300 for its collaborators. According to the company it will take on as many as 20 custom antibody projects per month.
