V preparation

The alkah manganates(V) in strongly alkaline solution (45—50% at 0°C) are all blue. In water these manganate(V) compounds instantly disproportionate into manganate(VI) and Mn02. Lithium manganate(V), prepared by reaction of LiMnO and excess LiOH at 124°C, is an exception. This compound is relatively stable in 3% LiOH solution at 0°C and in absolute methyl alcohol.

Dissolve TNBS in 0.1M sodium bicarbonate, pH 8.5, at a concentration of 0.01 percent (w/v). Prepare fresh. Note TNBS may be prepared as a stock solution in ethanol at a concentration of 1.5 percent. This solution is stable to long-term storage and may be diluted as needed in the bicarbonate buffer to the required concentration.

Autofluorescence of cells often complicates the studies with fluorescence microscopy (especially the application of green fluorescent substances). There are different reasons for the occurrence of this phenomenon (157) (i) the fluorescent pigment lipofuscin, which settles with rising age in the cytoplasm of cells (ii) cell culture medium, which often contains phenol red that increases autofluorescence (iii) endogen substances such as flavin coenzymes [flavin-adenine dinucleotide (FDA), flavin mononucleotide (FMN) absorp-tion/emission 450/515nm], pyridine nucleotides [reduced nicotinamide adenine dinucleotide (NADH) absorption/emission 340/460nm] or porphyrine (iv) substances taken up by cells (as mentioned above filipin) and (v) preparation of the cells fixation with glutaraldehyde increases autofluorescence.
