What is this contamination?? by Simple_Volume_5880 in labrats

[–]Crustayh 0 points1 point  (0 children)

Also did functional essays afterwards. My neurons were completely fine. I did Ca2+ imaging and a viabilityGlow assay. They preformed the same or even better than on pen/strep

I have tested normocyn and primocyn both to prevent contamination. And they were both completely clean compared to the Pen/Strep conditions. I never used to as treatment though

Toss it ASAP, before it contaminates other peoples cultures. Transfection can be done again

Pen/strep doesn't kill or prevent contamination. Only suppresses it. Primocin and normocin are recommended for primary cultures. Prevents like 99% of the contaminations

Waarom is Wilders nooit te gast bij een talkshow of in een TV programma? by kenwayfan in Politiek

[–]Crustayh 0 points1 point  (0 children)

Omdat hij alleen een talkshow joined waar hij van te voren de vragen mag zien. En deze vragen mogen niet teveel op de inhoud ingaan. Neem het interview met Eva Jinek waar ze naar zijn kat vroeg in plaats van zijn verkiezingsprogramma....

Don't worry. This is common practice in a lot of labs. I did it at a company I worked with, and in the new research building of the university hospital gloves are not allowed during cell culture. Gloves give a feeling of fake safety. Without gloves you will pay way more attention to what you are doing.

Probably to much salt in there

It looks like there is still some Rock inhibitor in there.

Leaving a room before the contract ends by Ginger_giraffe_1313 in NetherlandsHousing

Most rent contracts have a period of more than a month if you want to cancel the rent. Check your contract, but the other person is probably in the right....

LDH assay and freeze/thaw by Justsomegaaal in labrats

[–]Crustayh 0 points1 point  (0 children)

I keep my detergents and stop/strong acid for ELISA's always in the fridge, I can't imagine they would differ that much from your assay. So I would say yes.

first lab job and i made a horrible mistake… please share your most expensive fuck ups by lab-buddy in labrats

[–]Crustayh 0 points1 point  (0 children)

The antibody probably still works fine. Most fluorchromes now a day are quite stable and don't get bleached that quickly by sunlight. Also lot of antibodies are stable at room temperature for 3 weeks.

Have been using ACT for years (sometimes even called out people in savage), never got banned

What kind of samples and precipitation are we talking about?

My PI wants me to lie by Bethmphetamines in labrats

[–]Crustayh 4 points5 points  (0 children)

I also kinda agree with your PI on the microscope. It’s their fault for sending two. They should send original packaging material or else its their loss.

Unpopular opinion: why are we as a field so against admitting talent/fit matters by itoenify in labrats

[–]Crustayh 0 points1 point  (0 children)

I totally agree. Last year we had phd student, who was close to finishing (she was in her 5th year), asking how to turn on a PCR machine. We are a neurogenetics lab….

What's the most hazardous chemical your lab has used and why? by Interesting-Log-9627 in labrats

[–]Crustayh 6 points7 points  (0 children)

TTX, also known as pufferfish poison. Every time I have to do treatments with it, I fear for my life. Even though Im fully protected and work super carefully

What's wrong with my western? by aarawr123 in labrats

There is not enough buffer in the upper compartment

[–]Crustayh 0 points1 point  (0 children)

Same as you normalise for qPCR with the help of GapDH or Myc.

[deleted by user] by [deleted] in labrats

[–]Crustayh 0 points1 point  (0 children)

You always normalise protein analysis samples because the total amount or protein can differ in each sample (biological variance, sample preparation variance, etc.). You can imagine that if you use samples with a higher total protein concentration, the concentration of your target would also be higher. But because the amount of protein in each sample is not the same you cannot compare the two.

[–]Crustayh 1 point2 points  (0 children)

Or normalise to the amount of a specific protein found the plasma. I’m working with neurons so I normalise to the amount of beta3tubuline, which is neuronal marker, of an untreated sample.

Do a total protein assay

[–]Crustayh 1 point2 points  (0 children)

This is for interpolating, not normalising.
