Envirologix: Putting Science to the Test

Diagnostic Breakthrough - QuickBead™ Technology for Sample Preparation

June 1, 2007 -- EnviroLogix is pleased to announce another diagnostic break-through: QuickBeads™ that allow capturing target bacteria for further PCR testing or even other testing applications.

Our newest product, the QuickBead Kit for Bacterial Fruit Blotch (BFB), is the first commercial kit of prepared immunomagnetic beads (IMBs) to be used for the detection of BFB in seed washes. The beads are coated with antibodies specific to Acidovorax avenae subs. citrulli (Aac), the causal agent of BFB. Our IMBs allow sensitive and specific capture of Aac from seed wash extracts, expediting clean downstream analysis of the bacteria.

The coated QuickBeads trap the Aac bacteria on the surface of the beads. Exposing them to a magnetic field allows the separation of the beads (along with the bacteria) from unwanted material, thus yielding a clean and concentrated sample of the organism. This technique is known as Immuno-Magnetic Separation (IMS).

IMS combined with PCR (IMS-PCR) is a valuable technique for the detection of Bacterial Fruit Blotch in seed washes. The use of IMBs for IMS-PCR-based detection of BFB has been characterized and documented by Dr. Ron Walcott, Associate Professor of Plant Pathology at the University of Georgia.

Now testing labs can have highly sensitive and well characterized antibody-coated magnetic beads for IMS-PCR analysis at a fraction of the cost of coating their own.
