av A Rydén · 2011 — In addition to a markedly altered immune profile during the pre-diabetic phase, T1D Real-time reverse transcriptase polymerase chain reaction (RT-PCR). plasma glucose above 11.1 mmol/l, 2 hours after an oral glucose tolerance test heparinised blood samples were initially diluted 1:2 in room tempered RPMI 1640.
Equipment in PCR Laboratories To ensure that pre-PCR and post-PCR events remain separated, each room must have its own separate set of equipment, including pipettors, reagents, pipettor tips, racks, and so forth. Moreover, these items should not leave the area to which they are assigned. Each At a minimum, two areas should be designated for PCR testing: Pre- and Post-PCR. One room or area should be designated specifically for Pre-PCR. Optimally, this room should be further divided into two areas, PCR master mix preparation and sample preparation/addition to master mix. Sample preparation may involve a manual or automated extraction. Pre-PCR and Post-PCR areas should have independent environmental control, not use common ductwork for air conditioning and need to be separately adjusted in each lab.
I failed to persuade her that it's much safer to at least seperate pre-PCR from Post-PCR activities . Some say 4 rooms have to be used . One for PCR reaction set-up , a second for DNA extraction , a third for the thermocycler and the fourth for post amplification activities ( electrophoresis ) . A Pre-PCR lab coat must be worn in the Pre-PCR room at all times and left in the Pre-PCR room. No post-PCR ice buckets are allowed in the Pre-PCR room. Any racks or containers that have been in contact with the post-PCR area (including thermal cycler) must be decontaminated in bleach before being brought into the Pre-PCR area.
(17). In the conventional PCR system, pre-PCR and post-PCR steps were carried out by different persons in dedicated rooms. As one person performed the whole Lightcycler PCR procedure and occasional breakage of capillaries caused the risk of amplicon contamination, the UNG decontamination system was incorpo-rated into the protocol.

The layout of your lab makes it easy to keep your pre-PCR and post-PCR areas separate. Ideally, these two areas should be different rooms with airlocks between them to reduce the potential for contamination. If this is not possible, special care must be taken so that dedicated equipment, from refrigerators to pipettes, are used for each area.
Use 5 ul of RNA per reaction. • Each room and/or work area should have its own centrifuge, vortexers, pipettors, gloves, coats, etc. • For example, never “borrow” a post-PCR pipettor for use in a pre-PCR room without thoroughly decontaminating the pipettor first.

to avoid pre PCR and post PCR activites should be in different areas of the lab or different rooms. pre amplification. isolation of nucleic acid and assemply of PCR reagents in a "clean room" post amplification. PCR amplification, detection of PCR products in a "dirty room" prevent contamination.
Use physically separated pre-PCR and post- PCR 13 Sep 2017 This did not affect the apparent size of the repeat tract after agarose gel amplicons degraded completely at room temperature over a period of 3 days (Fig . 2).
