Bromothymol blue is an indicator with a K(a) value of 6xx10^(-5). What % of this indicator is in its basic form at a pH of 5 ?
The chosen dye should not be reactive or alter the DNA. Bromophenol blue is a dye used to track smaller sized DNA strands containing about 400 base pairs, while xylene cyanol is better for larger DNA strands with up to 8,000 base pairs. The chosen dye should not be reactive or alter th...
The microalga Haslea ostrearia (Gaillon) Simonsen is a marine pennate diatom that produces the very unique blue pigment marennine (Figure 1). This pigment is water-soluble, and it can be fixed on the gills of many invertebrates, particularly oysters (the so-called ‘green oysters’). The ...
