Unlike traditional lipophilic membrane dyes like DiO and DiI, CellBrite™ Fix dyes are fluorogenic lipophilic dyes that covalently bind the surface of live cells. The staining is simple, rapid, and much more uniform than other membrane dyes. Most importantly, surface staining is retained after fixation and permeabilization for immunofluorescence or other co-staining.

A rapid and inexpensive fluorescence method for screening conditions that affect protein thermal stability, such as protein mutations, ligand binding, and buffer formulations (like pH, salts, detergents, and other additives).

Mix-n-Stain™ Total Protein Prestain Kits are a new method for super-sensitive protein quantitation by  SDS-PAGE or western blot. Using the kits, you can quickly and easily label proteins in lysates or purified proteins with near-infrared CF® dyes before electrophoresis and blotting. The labeling can detect as little as 1 ng protein in an SDS-PAGE gel.

Proteintech Group, the benchmark in antibodies, today announces an agreement to purchase HumanZyme.  HumanZyme is a leading manufacturer of recombinant human proteins. Their proprietary human cell-expression system generates authentic human proteins that have greater biological activity and stability than competitors’ systems. 

Cell culture laboratories working with sensitive cell types can now benefit from a patented new technology, developed to revolutionize cell culture management and ensure optimal sample security across gene therapy, cell therapy and regenerative medicine applications development.

Life science researchers working across many applications can now benefit from the first-ever web-based pipetting application, developed to enable seamless connectivity with electronic pipettes for optimized performance and safe, efficient and rapid sharing of protocols.
