Fixative reagent
WebFixative: The fixative is a mixture of buffered chemicals that is made in the fumehood just prior to fixation due to the chemicals toxicity. For example, commonly used aldehyde fixatives in the BIF are 2.5 % Glutaraldehyde and 4 % formaldehyde in 0.1M Sodium cacodylate buffer. Depending on the sample being fixed, the choice of fixative will vary. WebIHC Zinc Fixative is an alternative fixative to formalin fixation of tissue for paraffin embedded sections. 10% neutral buffered formalin fixes the tissue by cross-linking proteins that may cause a conformational change or "masking" of the antigenic epitope leading to reduced or absent antibody reactivity.
