Description 1. This sample comes as 5 vials containing matrix material and 5 vials containing a microbiological pellet. 2. The purpose of this sample is identification of which samples are STEC positive and which are STEC negative. 3. The analysis of these samples is time sensitive. Please read the instructions and make sure you fully understand them prior to starting the analysis. 4. Analysis should be completed 1 hour of hydration of disk. 5. Each sample vial is uniquely marked. Remember to label your containers with the corresponding sample number and the study number prior to hydrolyzing the samples. 6. We do not provide buffer solutions with these samples. Please proceed to use your laboratory′s standard buffer or saline solution. If your laboratory does not have buffer in-house, we recommend using P3813, Phosphate Powder which can be purchased at SigmaAldrich.com.
Preparation 1. Allow the capped sample vials to equilibrate to room temperature. This may take about 15 min. 2. Aseptically transfer the pellets to the corresponding matrix vial. 3. Transfer the buffer solution/ hydration fluid to the vial. Vortex mix. 4. If PCR is used, hydrate the matrix-sample mixture with your recommended buffer (skip this step if not using PCR) 5.
