Can we vortex primers?

Can we vortex primers?

Method. Centrifuge the tube for a few seconds to get all the DNA to the bottom of the tube. Resuspend in TE buffer, pH 8.0 at a concentration greater than 10μM. Allow to sit for 2mins, then vortex for 15s.

Can you vortex PCR primers?

Do not vortex PCR mix. Add DNA polymerase (Taq) to the reaction tube last. Avoid overloading PCR products into the gel; this may result in cross-contamination or misinterpretation of the results.

What should you not vortex?

You should not vortex plasmids (especially big ones) or genomic DNA, because vortexing will shear long pieces of DNA into smaller fragments.

How do you resuspend primers?

This can usually be found on the tube itself or the primer sheet supplied with the order. For every 1 nmoles, add 10 μL of PCR-grade water. For example, if a primer states 19.4 nmoles, then add 194 μL of PCR-grade water. Mix the solution by vortexing to reconstitute the primers.

Can I Vortex master mix?

Best! I wouldn’t recommend vortexing SYBR Green, either before or after making the master mix. I briefly vortex and spin down the primer of interest, mix the total master-mix (with sybr) by inversion, and do a quick spin down (a pulse or so). Vortexing after adding Sybr poses the risk of damaging the Taq pol.

Can enzymes be Vortexed?

The vortexing is gentle enough if no bubbles are created. For a small protein like RNase, this should be fine. It is universal that any enzyme or protein is viable for long term at low temperature like -20 or -80 degrees and should not vortex harshly due to which enzyme may denature and lost its activity.

Is it OK to vortex Cdna?

Vortexing can shear cDNAs. You can finger flick the tube and quick centrifuge or pipette up and down a few times. Don’t vortex nucleic acids. As mentioned above either finger flick your tube followed by a quick pulse or gently pipette several times.

Can you vortex SYBR Green?

I wouldn’t recommend vortexing SYBR Green, either before or after making the master mix. I briefly vortex and spin down the primer of interest, mix the total master-mix (with sybr) by inversion, and do a quick spin down (a pulse or so). Vortexing after adding Sybr poses the risk of damaging the Taq pol.

Can you vortex oligos?

During the dry-down process, oligos form a white flakey pellet at the bottom of the tube. If resuspension is difficult, try heating the oligo at 55°C for 1–5 minutes, then vortex thoroughly.

Can you use water instead of TE buffer?

If you “just” have samples from cells etc. that are easily reproducible or you don’t need them for longer time, you can just use water! The pH of TE buffer is slightly basic however water have slightly acidic pH.

How much DNA do you need for PCR?

Normally used concentration are 100-250 ng for mammalian genomic DNA and 20 ng for linearized plasmid DNA (circular plasmid DNA is slightly less efficiently amplified) per 50µl reaction.

Can you vortex RNase?

Can You vortex primer too much?

Don’t vortex too much. But you can vortex gently for 5-10 for proper mixing. It would not break primers. Can you help by adding an answer? How to prepare a primer solution?

Is vortexing OK or just a plain no-no?

Are vortexing OK or just a plain no-no? Vortexing genomic DNA is not a good idea, it leads to breakage of DNA strands. For that matter, any sort of mechanical pressure (like vigorous mixing etc.) increases the chances of your ending up with sheared genomic DNA.

Do you vortex the master mix?

But I DO briefly vortex the master mix (I now use a supermix and just add primers) and then quick spin to get the liquid out of the lid. In the olden days, the theory was that you should never vortex enzymes since it was thought that would shear them.

Do you vortex your enzymes before mixing?

No mixing then. But I DO briefly vortex the master mix (I now use a supermix and just add primers) and then quick spin to get the liquid out of the lid. In the olden days, the theory was that you should never vortex enzymes since it was thought that would shear them.
