I want to extract bacterial DNA from various food matrix which have inhibitory influence on PCR reaction. In Biorad catalogue i have read that the 200-400 is designed for DNA extraction but 100-200 is more often found in references.

Hi I want to use Chelex 100 resin to extact DNA but in catalogue i found two kinds of this reagent (with dry mesh size 100-200 and 200-400). Do you know practical differences between these reagents?

Hello, I would like to know if you have experience with Salmonella detection kit (for real time PCR) from Roche (Lightcycler foodproof Salmonella detection kit) or Bio-rad (iQ-Check Salmonella kit). I have read that this second kit has been approved by AFNOR (Association Française de Normalisation). However, I could not find more information about validation of this method on food and feed matrixes.

I have heard about bioprotein derived mainly from Methylococcus. Here is the SSC report about it: http://europa.eu.int/comm/food/fs/sc/scan/out114_en.pdf Rafal
