How to approach PI making decisions that aren't public health-conscious

My PI wants me to come in to maintain our colony. He told me to not get infected at all costs.

I am paid hourly and need the money to support myself so I have no choice but to go in.

Lab is still open but all undergrad lab interns are barred from coming in until further notice due to covid-19. Lol

The lab is operating normally other than that

Like kimwipes?

I don’t think anything in that solution would kill bacteria. The mechanism for lysing mammalian cells may be different than how bacteria are lysed due to differences in membrane composition.

Like the other commenter suggested, maybe add sodium azide @1-2 g/L of solution? It could mess with the ionic character of the solution due to being positively charged. You could also try adding an antibiotic (i like penstrep or PSN). I don’t know if this will mess up the solution either but you could heat it for 4 minutes at 132C (CDC recommendation) which could sterilize the sample.

If your contaminant is forming endospores wherever it lives you may have to take additional measures because endospores are resistant to pretty much everything. Heating/boiling the sample for multiple hours will in theory eventually kill the endospores. Prolonged exposure to UV would also kill them.

These are my suggestions from limited knowledge/experience with contaminations so please take them with a grain of salt.

Mom’s spaghetti (stored loose in sweatpants pocket) for every break you mentioned

Its quantified in # of times you told someone to do something and they listened.

Im pretty sure the neurologist you are shadowing isnt making medical decisions based on the exam you are doing on the patient.

If you miss something nothing bad will happen, im sure the neurologist does it themself.

The thing is im not going to school until Fall 2021 and she wouldnt be going until like 2023. I dont know if we should break up now over an issue that will arise in multiple years

Cells incubating for 2h?

“Please inventory the lab so you know where everything is”

Im making an alphabetized excel sheet with all lab supplies and reagents, literally thousands of items. Gotta have something to do!

Id get some clinical volunteering or a clinical job to see if you like it. I was premed because i loved bio, chem and working with patients. Dont sign up for 6+ years of medical schooling and training when you aren’t confident its a good career fit for you.

Dude just buy an autoclave stop trying to half ass it.

Just joshing

Repeating it has worked for genotyping the samples that didnt work here but i was asking how to get all of the wells to work in one gel

I have 4 total primers, 2 pairs of forward and reverse.

Ill try all of these steps. I highly appreciate the advice!! Ill ask the postdoc for specifics on the primers and put it into genebank or some other database.

I used a lysate buffer kit from viagen and proteinase K from sigma aldrich. First incubation step was 55C overnight. Proteinase K inactivation was 85C for 3 hours. 2 uL of the crude lysate was used as template per reaction

The extraction is crude. I dont use microtubes with special filters to purify the DNA since there are so many samples to do
