Damania Lab Discovers Gene That Suppresses Herpesviruses
In a paper published by Cell Host and Microbe on Feb. 13, a research team led by Blossom Damania, PhD, of the Department of Microbiology and Immunology and member of the UNC Lineberger Comprehensive Cancer Center, found that suppressing the TLK enzyme causes the activation of the lytic cycle of both EBV and KSHV. During this active phase, these viruses begin to spread and replicate, and become vulnerable to anti-viral treatments.

Automation Of A Homogeneous Proximity Assay For Detection Of Residual Protein A In Biological Therapeutics
Protein A is used in affinity chromatography for therapeutic antibody purification and has been shown to leach from columns during purification of antibodies resulting in contamination. Residual Protein A in therapeutic drugs could elicit mitogenic or immunological reactions in patients.

Mixed-mode chromatography resin is a top tier selection for the manipulation, purification and handling of molecules; providing an unmatched level of separation properties and resolution. The combination of cation exchange resin and metal affinity resin properties, allows multimodal chromatography to provide an access route for biomolecules to separate and the use of alternative chromatographic methods make these biomolecules seem homogenous.
A proven method for confirming protein purity and yield without the need for gel staining steps. Stain-free gels provide visual confirmation of protein purity and yield by gel electrophoresis in less than 30 minutes. Stain-free technology is perfect for drug discovery, drug development, and method development for preclinical research.
CHT is a leading purification medium of biomolecules in today’s demanding downstream process industry. Its mixed-mode support offers unique selectivities and often separates biomolecules that appear homogeneous with other chromatographic methods. The diverse binding capabilities of CHT for host cell proteins, leached protein A, antibody dimers and aggregates, nucleic acids, and viruses allow its use at any stage from initial capture to final polishing.
