PPT-Fixation and Fixative Prepared by : Reem Aldossari

THE GENERAL VISCRA OF THE RAT Definition of Fixation In the fields of histology pathology and cell biology fixation is a chemical process by which biological tissues are . FIXATION AND PERMEABILIZATION IN IHC/ICC FIXATION: Fixation should immobilize antigens while retaining cellular and subcellular structure. It should also allow for access of antibodies to all cells a The main purpose of fixation is: 1) to cross-link cellular structures into a matrix so as to preserve the structure of the cells with the minimum of alteration from the living state (i.e. with no ch For 100ml put 10 ml 10% PBS in a 500ml beaker Add 40ml water pH to 11.00 with NaOH Weigh out required amount of paraformaldehyde in fume hood Put stirrer into fume hood and stir in paraformaldehyde un Processing in Autism.
