Re: centrifugation of hemocytes

... time to adhere), and centrifugation at 400 for 5 min, I gently took off the medium and resuspend the cells by pipetting thoroughly up/down: the viability worked well. However, that time i skiped the washing step (and wait 24h...), which can be annoying when working with different dyes... I will ...

... plates, flat-bottom and round bottom). I took the supernatant off and tried to resuspend the cells with PBS and then performed my classical viability protocol… But the cells have gone… These velocities are the one used in articles… and i can't increase the velocity of centrifugation because ...

Re: Gender divison in two opposites is greatest mistake of manki

... plan behind it? We are supposed to be dead by that time. Thus, menopause is a redundant pathway to assure integrity of genetic information and viability of the offspring: prevent late reproduction = lower chance of passing on damaged DNA and/or RNA. Male reproduction is modified with age as ...

Re: Theories - Origin of Life

... an intermediate group of Niss-yota parts that were lost during speciation. In that case, the initial population should show a wide range of hybrid viability, and the separated populations should not produce hyrbids that consistently fall below that range of viability. Of course, hybrid viability ...
