New Products: UHLPC Columns from Agilent and More

Premium

Agilent this week introduced its new high definition Zorbax 300-SB-C3 and 300-Diphenyl 1.8µm columns for reversed-phase liquid chromatography.

The new C3 phase broadens selectivity and improves peak shape and recovery for larger proteins while the diphenyl phase provides additional selectivity through pi-pi interactions with aromatic amino acids, the company said.


Bio-Rad has launched its new Mini-Protean TGX Stain-Free precast gels with a trihalo compound that allows for fluorescent detection of proteins without staining.

The gels allow for protein separation, imaging, and analysis in 20 minutes, compared to up to two hours for standard Coomassie protocols, the company said.
