Determination

(Science: cell biology) The committment of a cell to a particular path of differentiation, even though there may be no morphological features that reveal this determination. Generally irreversible, but in the case of imaginal discs of drosophila that are maintained by serial passage, transdetermination may occur.

Protein concentrations:Can it drastically change its effect?

did you do some determinations at various intervals of time after treatment? Here is an idea: inoculate your protein on your culture, then after 6 hours take the flasks out of the incubator and freeze the cells. After 12 hours take ...

O.D. and cell number

I am afraid you cannot do that. It depends on the type of bacteria. From what i know, when you start with a culture, you first need to do paralel determinations with the spectophotometer and serial dillutions, and only then can you use OD

A Monkey's Uncle

... my help). Nor am I seeking to change anything within the realm of the biological sciences. My argument is that we seem not to be able to agree on determinations where, if we are talking science, we should be in agreement. And if we are not in agreement, then there is something wrong. Let’s define ...
