Located in Palmerston North, New Zealand, PolyBatics was created to commercialize biobead technology created by Professor Bernd Rehm at Massey University.
PolyBatics harnesses the natural power of cells to create natural polymer particles, or biobeads, covered with proteins engineered to perform specific functions.
whose novel biobead platform offers applications for diagnostics, antigen delivery/vaccines, bioseparations and many other uses, today announced the start of field trials of a unique tuberculosis (TB) skin test based on the company's bionanoparticle technology.
PolyBatics biobeads represent an ideal platform for either diagnostic or vaccine applications, given their unique ability to consistently display antigens of choice on the biopolymer nanobead surface and their low-cost single-step production," said Tracy Thompson, PolyBatics Chief Executive Officer.
The water was pumped constantly through a filtration system, UV sterilizing chambers and a column containing biobeads with established bacterial cultures.
Eluted samples were evaporated to 1 mL under a gentle stream of nitrogen and applied to gel permeation chromatography columns packed with Biobeads S-X3 (Biorad Laboratories, Hercules, CA, USA) and eluted with hexane: dichloromethane (1:1 by volume).
BioBeads are 6 mm in size and contain more than a billion beneficial live cultures in a proprietary blend of four probiotics, which mimics the strains found naturally in the stomach and intestinal tract.
To ensure complete recovery of activity, the detergent was removed from the medium by adding adsorbent polymeric Biobeads SM-2 (100 g/L) to the samples, which were then shaken for 2 h at 4 [degrees]C (9).
The supernatant was defatted by gel permeation chromatography on BioBeads SX-3 (100-200 mesh; Bio-Rad); the eluting solvent was ethyl acetate: toluene (3:1).
