How Cassia Tora powder (Cassia obtusifolia) can be fully solbilized in water?

The filtration cassia powder is very low. It passes only 20-40g throug 63/74 micron/cm2 mesh even after the modification with Sodium chloroacetate. Therefore, it has biigeer solubility issue. So,...

How one could extract 100% (or near to 100%) DNA and RNA from a known bacterial biomass and quantify?

Here 100% extraction means a total DNA and RNA extraction from known bacterial biomass. This will not for the quality check but more on the quantification. If there is any published method...
