How do you maintain a thermal cycler?

How do you maintain a thermal cycler?

Clean the housing or external part of the thermal cycler with a soft cleaning cloth or paper, this should be lightly moistened with a soap solution of neutral pH, otherwise you can use the cleaning cloths of computers which can be purchased in any dedicated house ( do not use waxes or abrasives).

How do you maintain a PCR machine?

Do not use any tube or plate that is not appropriate for the PCR machine you are using.

1. Make sure tubes and especially plates are well sealed before you begin run.
2. Clean up any spilled solutions and dispose of in appropriate biohazard boxes.
3. Be careful with PCR machine lids.
4. Turn PCR machine off when you are done using.

How do you decontaminate a thermal cycler?

How and when to decontaminate. Generously spray workstations/equipment/pipettes with 10% bleach, then let it sit for 15-30 minutes (coffee break time!). Then wipe up the bleach and follow up with a water rinse and wipe — bleach is corrosive, so it will damage materials if residue is not removed by rinsing with water.

What does a thermal cycler do?

The Thermal Cycler (also known as a Thermocycler, PCR Machine or DNA Amplifier) is a laboratory apparatus used to amplify segments of DNA via the Polymerase Chain Reaction (PCR).

What is the important of thermal cycling in PCR testing?

The Thermal Cycling Process The actual PCR process is conducted via thermal cycling, a process of heating and cooling that creates the conditions necessary for DNA replication. This final increase of temperature allows the Taq polymerase enzyme to actually replicate the template DNA.

What is ramp in PCR?

The ramp rate of a thermal cycler indicates the change in temperature from one PCR step to another over time and is usually expressed in degrees Celsius per second (°C/sec). The terms “up ramp” and “down ramp” refer to the heating and cooling of thermal blocks, respectively.

Do we need to calibrate Qpcr machine before every run?

To ensure optimal performance of the thermal cycler or Sequence Detection System, it is strongly recommended that the thermal cycler is calibrated regularly.

Does bleach destroy DNA PCR?

Avoidance of contamination in the PCR laboratory requires the use of strict precautions. Because of its high efficacy, low cost and relatively low corrosiveness, we recommend the use of ten percent Clorox as a decontaminant for elimination of DNA templates in the PCR laboratory.

How fast does bleach destroy DNA?

Household bleach (sodium hypochlorite) is effective for removal of DNA from surfaces [2]. Use freshly prepared solution of household bleach (1 % sodium hypochlorite) [3] for 30 minutes of contact time on the surface followed by rinsing with ethanol or water.

How much does a thermal cycler cost?

A simple PCR machine like Bio-Rad T100 thermal cycler has a list price of 4912 USD (with a promotional price of 2595 USD in the US) as of Jan 30, 2019. The cost of rtPCR systems ranges anywhere from 15,000$ for some RotorGene models to over 90,000$ for QuantStudio 12k.

Who invented thermal cycler?

Kary Mullis
Kary Mullis is generally credited with inventing PCR in 1983 while working for Cetus Corporation in Emeryville, California.

How long does a thermal cycler take?

Each successive cycle results in the doubling of the DNA copies. The duration of time spent on thermal cycling will vary depending on the volume of the sample and the specific equipment that’s used but it typically takes between one and four hours.
