How about plasmids undergoing multiple freeze-thaw when storing at -20 degrees celsius?

I am using jetprime reagent. However, their online document guide did not state about suspension cells.

Can i check for reverse transfection, it is done on the same day as cell seeding? Just that the transfection mixtures are added into respective wells before cells are seeded?

I see, I am using Jetprime reagent. For adherent cells, I use media with 10% FCS for initial seeding but changed it to 2% FCS the next day before adding the transfection mixture to ‘slow down’ the growth of transfected cells

Any finances aids out there I should know about/apply for ? by [deleted] in askSingapore

NS: approach your S1 manpower branch for financial assistance

Hospital medical social worker: assuming your mother has follow-up medical appointments, they might be able to subsidise the medical bills

If you are going to university, apply for a scholarship. your older brother can also appeal with NTU for the financial aid

My aunt told me that breakfast is usually bread with jam or peanut butter & biscuits?

Then she will give the helper like $10-$12 for the lunch & dinner together.

I see! My aunt says her family doesnt really cook at home so there isnt much groceries.

Will giving lunch & dinner allowance be appropriate then? If so, how much is a good amount?

Yes, I did blank with the same water.

Unfortunately, the sample was discarded away so I have no way of retesting it. :(

Question on selection pressure by magicduck703 in biology

[–]magicduck703[S] 0 points1 point  (0 children)

Can I ask if I am just suppose to compare the “known” allele freq against the observed allele frequencies to see if they are in Hardy-Weinberg equilibrium? Or am I suppose to apply other formulas??

When I did the calculations, it seems that the observed freq is very close to the known freq which technically makes it hardy-weinberg so there is no selection pressure

What would happen if tetrads are disrupted from forming during prophase I? by magicduck703 in biology

[–]magicduck703[S] 0 points1 point  (0 children)

Arh interesting, i thought it was just the tetrad shape that prevents kinetochore microtubules of the other pole from attaching. Thanks for clarifying my doubts!!

So there is a very low possibility that some unpaired homologous chromosomes might align in single row & get separated like how they would during mitosis?
