Biological Activity
It is found that the trypanocidal dye Hydroxystilbamidine bis(methanesulfonate) permits the recovery of mRNA after polysome released with Nonidet P-40 (NP-40). Sucrose gradient analysis of detergent-lysed postnuclear supernates is used to analyze the size distribution of NP-40-released polysomes. The heparin gradient shows some polyribosomes, whereas the Hydroxystilbamidine bis(methanesulfonate) gradient shows a remarkably large peak of very heavy polyribosomes. This peak is obtained reproducibly if Hydroxystilbamidine bis(methanesulfonate) is present before the addition of NP-40[1].

Protocol
Silkwork larvae are used in this study. Larvae on the fourth or fifth day of the fifth instar (~4.2 g body weight) are injected with 35 μL of a solution of 10 mg/mL cyclobeximidein H2O. After 5 min, the animals are immobilized in ice, and posterior silk glands are dissected and washed in ice-cold 0.15 M NaCl, 0.015 M Na citrate, 100 μg/mL cycloheximide. Washed glands from two larvae are placed in a homogenizer containing 4.7 mL of 40 mM triethanolamine-HCl, pH 7.5, 0.15 M sucrose, 0.1 M KCI, 3 mM MgCl2, 2 mM reduced glutathione, 10 μg/mL cycloheximide, 750 μg/mL Escherichia coli tRNA, and an appropriate concentration of RNase inhibitor (sodium heparin, 1.5 μg/mL or Hydroxystilbamidine bis(methanesulfonate), 1.5 mM)[1].

Mice (six per group) are given various doses of Hydroxystilbamidine bis(methanesulfonate) (HSB) 3, 2, and 1 day before antigen. Other groups are given Hydroxystilbamidine bis(methanesulfonate) 1 or 2 days after the injection of antigen. Another group of mice receive antigen and Hydroxystilbamidine bis(methanesulfonate) simultaneously. A control group receives only antigen. The antigen dose consists of 2×108 sheep erythrocytes (SRBC). Four days after the injection of SRBC, the mice are sacrificed and spleens are removed and assayed for plaque-forming cell (PFC) by the plaque assay[2].
