摘要: Abstract DNA concentrations, RNA and corresponding RNA/DNA ratios of the deposit-feeding bivalve Abra ovata were measured using seven spectrofluorimetric methods. Highly significant differences in found. The analysis effects main steps involved these protocols showed that: (i) presence detergent extracting buffer is absolutely necessary; (ii) centrifugation step essential; (iii) there are several problems associated with purification nucleic acids phenol-chloroform-isoamylalcohol (this procedure affected linearity response DNA-specific fluorochrome, modified responses two non-specific fluorochromes; moreover, this effect was dependent on BSA concentration). Based results, a protocol for quantification recommended.
