NEW PRODUCTS: Versalinx, Expressarray p53, BioCube System

Premium

Prolinx introduced two new products for protein detection called Versalinx rapid protein-enzyme conjugation kits HRP and AP. These kits incorporate the company’s Versalinx affinity technology for immobilizing macromolecules, which is based on the specific interaction between P(D)BA (phenyl(di)boronic acid) and SHA (salicylhydroxamic acid). The new products use the Versalinx complex to attach an enzyme molecule (horseradish peroxidase or alkaline phosphatase) to any protein probe.

 

Sense Proteomic last week launched its first functional protein array product, Expressarray p53. It contains wild type and mutant forms of the human tumor suppressor protein p53, immobilized in a microarray format. The company claims this is the first array of full length, functional proteins to enter the marketplace. Expressarray p53 is manufactured by the Genetix Group as part of a production agreement with Sense Proteomic.

 

Protedyne introduced a high throughput automation platform called BioCube System. It contains modules for multi-functional liquid handling and sample processing, robotic loading and unloading of up to 32 PCR machines and for automating agarose gel electrophoresis.
