question about G418 sceening test

... After 24hr incubation with 2 mL regular DMEM, I changed to DMEM with G418 with different concentrations. The G418 disulfide 50mg/mL stock in H2O was from Sigma(G8168). I simply added it to 2mL to create a 400,500,600,700,800,900 ug/mL serie. It has been reported that 700 ug/mL was used for ...

cellular mechanisms that result in symptoms of cholera

... ribosylate the Gs alpha subunit of the heterotrimeric G protein. This results in constitutive cAMP production, which in turn leads to secretion of H2O, Na+, K+, Cl−, and HCO3− into the lumen of the small intestine and rapid dehydration. The gene encoding the cholera toxin is introduced into V. ...

What is responsible for converting H2CO3 to HCO3- and H+ ...

... CO2 into the water? What reactions (and how quickly) will take place? I know that the following reactions should took place in the water: CO2 + H2O <=> H2CO3 <=> HCO3 + H But if I add CO2 into the water, the KH (alkality, which consist mainly of HCO3) does not change. So it means ...

What's the chemical reaction catalysed by nitrate reductase?

... per this chart http://i.imgur.com/ug3uF.png . I assume that in aerobic organisms the chemical reaction would be (NADH + H + 1/2O2) -> (NAD+ + H2O) but how does this work with nitrite reductase in anaerobic respiration?
