✦ Synopsis

Molecular weight of PHB becomes low when using a hypochlorite extraction method for PHB separation. This disadvantage was overcome by adding sodium bisulfite which is an anti-oxidant. The molecular weight drop was decreased from 30 % to 14 % by adding sodium bisulfite. It was also found that raising the pH to 12 and the addition of a surfactant resulted in the improvement of the PHB purity.

## Abstract Both spontaneous and evoked transmitter release from the frog neuromuscular junction can be modified by application of sodium bisulfite, a reagent specific for disulfide bonds. An increase in miniature endplate frequency is produced that is not dependent on external calcium, sodium, or
