Ph of hematoxylin
WebbWhether progressive or regressive, once the desired level of nuclear staining is achieved, hematoxylins are “blued.” At acid pH, hematoxylins stain the nuclei red. However, once … WebbHere we are describing steps for 4% PFA of the 1L solution. The same trend follows for other volumes as well. Take 800 mL of 1X PBS. Add 40 g of Paraformaldehyde powder to 1X PBS. Stir the mixture at 60˚C in ventilation hood (DO NOT Boil). PFA powder does not dissolve instantly, you need to raise the pH of the mixture by adding 5N NaOH drop by ...
