A display of nucleic acid green faction Well Ning (Methyl green-pyronln) staining: ⑴ Principle: A green and basic dyes are sent Ning Well, the two nucleic acids (DNA and RNA) can be dyed separately, the mechanism may be that the two nucleic acids polymer molecules are animal tissue sections, but with varying degrees of polymerization. A green has two amino tissue slices manufacturers charged, but rather only one faction Well. Therefore, in the mixed dye, the result of competition between the two is that the higher the degree of polymerization A green easy and DNA-binding blue-green, but rather is associated with lower faction Well degree of polymerization of RNA binding is red. (Reagent preparation and histological methods are detailed technical monograph) ⑶ results: nuclear DNA was in the blue-green, nucleolar and cytoplasmic RNA was pink. 2, dehydration: the removal of moisture within the organization, by some vehicle replacement process of moisture within the organization. Usually after internal fixation of tissue often contain more water, but the water is not mixed with wax, so that must be removed before dipping wax tissue mass in the water. Ethanol is the most common dehydrating agent, can be mixed with water ad libitum tissue slice process, dewatering capability, and the hardened structure. Fast penetrating tissue tissue sections, often resulting in tissue blocks shrink, become brittle. Thus, the use of ethanol dehydration, they should start with a low concentration began, and then followed by increasing concentrations of ethanol, using different concentrations of ethanol and water gradually displace tissue within the block.
