What is a PCR workstation?
What is a PCR workstation?
A polymerase chain reaction (PCR) workstation, a workspace enclosed on three sides, provides the space for doing amplification of DNA and RNA. These workstations, used in biology and genetic laboratories, prevent cross contamination between samples and UV lights for sterilization.
Is PCR cabinet a ventilated enclosure?
The PCR-NV cabinets provide a non-ventilated, circulation-free work area to reduce cross-contamination of samples in applications where laminar flow air is not required during PCR experiments.
Do I need a PCR workstation?
PCR workstations are designed to protect against contamination during sensitive PCR amplification and manipulation of DNA or RNA. Since minimizing cross-contamination in turn minimizes inaccurate results, PCR cabinets and hoods are useful additions to the molecular biology and genomics lab.
Do you need a PCR Hood?
PCR hoods are used in biology and genetic labs so that there isn’t any cross contamination between samples. PCR workstations have no circulation, which helps to prevent contamination, and UV lights for sterilization.
How do you clean a PCR Hood?
Wipe down exterior of PCR hood with 1% bleach solution, then follow by wiping down with water. Wipe counters with 1% bleach solution. Remove lab coats, wash hands, and do not reenter pre-amplification room until following morning.
What is a dead air box?
AirClean® Systems dead air boxes provide a circulation-free environment for the amplification and manipulation of DNA/RNA. Each dead air box is standard with the UVTect Microprocessor controller and a 254nm ultraviolet light source for irradiation between amplifications.
What is PCR Hood?
A PCR workstation, also called a PCR hood, is a work space, enclosed on three sides, that provides a space for doing amplification of DNA and/or RNA. PCR hoods are used in biology and genetic labs so that there isn’t any cross contamination between samples.
How do you decontaminate a PCR room?
The following procedures for DNA decontamination were employed: (1) spraying a 75% ethyl alcohol solution into the air before cleaning the rooms; (2) irradiating the rooms with UV‐light for 1 hour; (3) wiping objects and equipment in the rooms with a hypochlorite solution to remove settled particles; (4) wiping …
What does DMSO do in PCR?
DMSO is used in PCR to inhibit secondary structures in the DNA template or the DNA primers. It is added to the PCR mix before reacting, where it interferes with the self-complementarity of the DNA, minimizing interfering reactions. DMSO in a PCR reaction is applicable with high GC-content(to decrease thermostability).
How do you fix primer dimer in PCR?
i suggest one (or more) of the following solutions:
- increase the annealing temperature.
- increase time\ temperature of template denaturation.
- decrease primers concentration(10 pmol will be OK)
- use a PCR enhancer such as DMSO.
- Check out your template.
- use high quality Tag.
How do you clean a PCR workstation?
What happens if PCR is contaminated?
If DNA fragments from the lab environment, such as a DNA template amplified in a previous qPCR experiment, enter the qPCR reaction or reagents, even in small quantities, they can be amplified during the reaction. This contamination and non-specific amplification can cause misleading results, such as false positives.
Can DMSO inhibit PCR?
DMSO binds to the DNA and prevents the reannealing of single-stranded DNA. It also facilitates the annealing of primer with a templet. Therefore, it increases the specificity and yield of the PCR reaction.
Why DMSO is used in PCR?
Dimethyl sulfoxide (DMSO) is an organosulfur compound with a high polarity and high dielectric constant, that is used in PCR to disrupt secondary structure formation in the DNA template.
Why is DMSO needed in PCR?
Why choose Esco thermal cyclers for PCR?

German-made ebm-papst® permanently lubricated, centrifugal motor/blowers with external rotor designs.
What are PCR cabinets and why are they used?
In practice, all polymerase chain reaction (PCR) procedures are conducted in the same room. Under these circumstances, PCR Cabinets are used for reagent preparation and sample preparation to minimize contamination. Because of the high copy number generated during PCR, it is essential to prevent possible contamination of the PCR.
Which thermal cyclers are suitable for use with PCR kits?
Esco Swift™ MiniPro and Aeris™ thermal cyclers are applicable for use with different PCR kits and commercial mastermixes. User is advised to validate the reagent’s protocol before using it for multiple experiments or tests.
