Ion-selective electrode (ISE) is an important instrument for analyzing various electrolytes like Sodium, Potassium, Chloride, and Lithium in the pathology laboratory. ISE is used in many departments of the medical field. Principle of the ion selective electrode (ISE) ISE principle is that, it create potential that is proportional to the concentration of the tested analyte. … Read more
Heat fixation is the second method after the chemical fixation in histology. what is heat fixation in microbiology? The mechanism of heat fixation is, that it denatures the protein. It takes two to three minutes. Microwave ovens have overtaken the conventional heating method, due to their controlled environment. 45-55 C is the optimum temperature of … Read more
10% Neutral Buffered Formalin is widely used in labs for preserving biological tissues. It stabilizes tissue structures by cross-linking proteins, and the buffer system ensures a neutral pH, which helps reduce tissue damage during fixation. Here’s the composition of 1 liter of 10% Neutral Buffered Formalin: How to prepare 1 liter 10% neutral buffered formalin … Read more
It is fixation is important in tissue processing because it preserves the anatomy of different tissues. It makes tissue hard so that a thin section can be made from it. Tissue fixation means the process by which components of the cell and tissues are fixed physically and partially by chemical methods. So that it … Read more
