Comparison of the effects of a preliminary hepatic washing and of saponin on the intracellular penetration of peroxidase-labeled anti-rat albumin antibodies in hepatocytes

A CazierG Feldmann


The effect of a preliminary hepatic washing with saline before liver fixation either by perfusion or immersion was compared to the effect of saponin, a membrane-permeabilizing agent, in order to ascertain which procedure is best to obtain a homogeneous distribution of albumin-containing hepatocytes in the hepatic lobule. Albumin was located in the hepatocytes by peroxidase-labeled antibodies using light and electron microscopy. The efficacy of the two procedures on the intracellular penetration of labeled antibodies in liver sections was judged by preparing transverse ultrathin sections. Both procedures yielded similar results. Liver fixation by perfusion with saponin and without a preliminary washing, however, distributes albumin-containing hepatocytes more homogeneously in the hepatic lobule and enables labeled antibodies to penetrate more satisfactorily. In contrast, when the liver is fixed by immersion, the preliminary washing is the only way to obtain an even distribution of albumin-containing hepatocytes, as saponin is not effective under these conditions. In conclusion, the localization of albumin in the hepatocytes must be adapted according to the technique used to fix the liver.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.
