Synonyms Nested PCR Mycoplasma Detection Kit
Stability & Storage

Transported with ice packs. Store at -20℃ away from light, with a validity period of 18 months.

Background

The UA-Myco Nested PCR Mycoplasma Detection Kit is used for the qualitative detection of mycoplasma contamination in cell cultures. Over 95% of mycoplasma contamination in cell cultures is caused by Mycoplasma fermentans, M. orale, M. pirum, M. hyorhinis, M. hominis, M. salivarium, M. arginini, and Acholeplasma laidlawii. This kit amplifies the conserved gene fragments of these eight and many other common mycoplasmas in cell culture media using the nested PCR method to determine the presence of mycoplasma contamination. The kit features rapidity, high sensitivity, and high specificity. Each reaction can detect as few as 10 mycoplasma gene copies, with particularly significantly improved detection sensitivity for Acholeplasma laidlawii, and there is no cross-reactivity with bacteria or cultured cells.

Components

The nested PCR mycoplasma detection kit contains 2 tubes of ready-to-use primers and 1 tube of reaction internal control, with specifications as follows:

Specification

component

25T

One tube of Primer P1 (50 μL), one tube of Primer P2 (50 μL), one tube of PCR reaction internal reference (50 μL)

50T

1 tube of Primer P1 (100 μL), 1 tube of Primer P2 (100 μL), 1 tube of PCR reaction internal reference (100 μL)


Protocol

1. Preparation of cell culture medium to be tested
1) Take 1mL of cell culture medium from the cell culture in the logarithmic growth phase.
2) Centrifuge the cell culture medium at 200g for 5 minutes at room temperature. Transfer approximately 800μL of the medium to a new centrifuge tube, taking care not to introduce the precipitated cell debris.
3) Use the prepared cell culture medium as a template for nested PCR to detect mycoplasma.
2. Nested PCR reaction
1) First PCR reaction: Take the general 2X PCR premix reagent as an example:
PCR reaction assembly (preparation on ice is recommended))

2) Take 1 μL from the first PCR reaction as the template for the second PCR and perform the second PCR using primer P2. The assembly of the second PCR reaction (preferably prepared on ice) is shown in the table below. The PCR reaction conditions are the same as those for the first PCR reaction.

3) Prepare a 2% agarose gel. Take 10µl of the second PCR product for DNA electrophoresis.

3. Results
The internal control of the PCR reaction shows a single DNA band at 515bp. Common mycoplasma contamination produces a single DNA band ranging from 236bp to 365bp. Acholeplasma laidlawii contamination results in double DNA bands at 426bp and 219bp.

Guidelines

It is recommended that the PCR reagents be from the hot-start Taq enzyme series. The 2X PCR premix used should not contain DNA gel electrophoresis stain.

It is recommended to set up the PCR reaction in a clean bench to avoid cross-contamination and aerosol contamination. Use nuclease-free pipette tips and reaction tubes; it is advisable to use filter tips.

Without strict verification, it is not recommended to arbitrarily change the amounts of reaction reagents.

Aliquot and store the reaction reagents according to the instructions to ensure the stability of the reagents.

Needs editing
Format: Kindle
Cute storyline and promising characters, but the lack of editing is painful to read. I would love to read an edited version.

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it. I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!. I received a free copy of this book and am voluntarily leaving a review.

3 Star Read,
Format: Kindle
This book wasn't bad, but wasn't my cup of tea. It's highly disappointing because the storyline is so original. There is no real conflict or resolution, so the entire thing feels flat. As a lover of omegaverse books, I know there is a ton of variety out there, and ov is really up to the author. But this one is weird. Omegas have multiple scent glands all over their bodies and go into week long heats every month. Alphas have knots in the middle of their shaft instead of the base, and the knot doesn't always swell, no explanation of when or why. It doesn't engage at all when the mouth is in play. I also didn't enjoy the author's writing style. Each paragraph is only 1 or 2 sentences long, and the entire book reads very stacato. The conversations are stiff and unnatural feeling. Everything is very repetitive, both in word choice and in thought. The same thing is repeated 3 or 4 times over a single page, multiple times over. I ended up doing so much skimming. The first 50% of the book is all slow burn, and the last 50% is almost straight mediocre spice. This wouldn't have been all bad if the grammar and spelling errors didn't start at the exact same time. Tongue is repeatedly misspelled in the middle of the spice.

Cozy Omegaverse
Format: Kindle
This is the true definition of Cozy Omegaverse. LA wedding coordinator meets her pack at the location for a couple’s destination wedding. Low angst because they are scent matched high heat with heats and knots. Everything you love about this genre with very little anxiety. Simply a fun experience to read and a book I will comeback to when I’m in a slump. I simply love reading this book
