Immersion fixation can produce useful corroborative evidence but any micrographs from either fixation must show resolvable unit membranes if it is to be used to support a mechanism for MFGM formation. BTN has previously been localized with immunocytochemistry to the apical plasmalemma of the mammary cell in several mammals and around the MFG in the… Continue reading Immersion fixation can produce useful corroborative evidence but any micrographs from either fixation must show resolvable unit membranes if it is to be used to support a mechanism for MFGM formation
