The accuracy values were compared and analyzed statistically (Table9). enzyme It cannot distinguish between live and dead cells and must work within certain absorbency (more than 107 and less than 108). A 2x10-6 dilution of your bacterial culture yielded 10 colonies. Iron is colored orange and dioxygen is colored red. For the drug to be made available to the population safely and with therapeutic efficacy, therapeutic monitoring of the drug is necessary. Turbidity measurement can be done without destroying the sample. The main disadvantages are: 1 It is an oligomer of two light (11 kDa) and one heavy (13 kDa) subunits with a total molecular mass of approximately 36.5 kDa. The disadvantages are that it is time consuming, expensive and therapeutic ranges do not yet exist for many drugs. A spectrophotometer or calorimeter can be used for turbidimetric measurements of cell mass. It does not give you cell numbers or increase in mass. The concentrations used were 100, 140, and 196g/mL. In the microbiological test the drug under study must present a relevant response under the microorganism tested (1, 37).
