Novel Chelator and Use Thereof

The present invention relates to dimeric pentadentate chelators with exceptionally strong binding of metal ions, for detection, immobilization and purification of biomolecules. Dimeric chelators offer a cooperativity of binding of two adjacent immobilized metal ions simultaneously to a histidine-tagged biomolecule, which gives advantageous properties regarding strength of binding compared to a corresponding monomer chelator. In addition, a dimer increases the selectivity (ease of separation) against non-tagged biomolecules with low metal-ion affinity.

20180171484 · 2018-06-21 ·

Spheroidal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by dispersing a polymerizable monomer phase over double-walled cylindrical cross-flow membrane into an suspension phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the suspension phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The membrane is metallic and includes a superhydrophobic coating.

Integrated process to recover a spectrum of bioproducts from fresh seaweeds

An integrated process for the recovery of a spectrum of commercially valuable products such as agar, cellulose, lipids, pigments and a liquid rich in minerals of agricultural importance directly from fresh seaweed without employing any catalyst driven in situ chemical conversions. Also solvents used during lipid extraction were shown to be used for three cycles without affecting the yield and quality of successive products. Furthermore, this new process is highly efficient and utilizes total seaweed raw material without any leftover biomass as solid waste.

Chelator and use thereof

The present invention relates to dimeric pentadentate chelators with exceptionally strong binding of metal ions, for detection, immobilization and purification of biomolecules.
