Antigen Isolation and Purification
An antibody was raised against a protein isolated from the cytoplasm of mesothelioma cells. It was subsequently used in an immunoperoxidase procedure on formalin fixed, paraffin embedded tissue sections. A representative sample of benign and malignant tumours from all the systems of the human body was examined. All the tumours derived from coelomic surfaces (mesotheliomas of pleura, peritoneum,...
متن کاملIsolation and Purification of Dna
IMPORTANT NOTE: The smallest amount of contamination of DNA preparations by recombinant phages or plasmids can be disastrous. Many person-years have been wasted reisolating previously cloned sequences that contaminated preparations of DNA used to create recombinant DNA libraries and many researchers have been embarrassed to find that the “extra” genes they found on their Southern blots were act...
متن کاملPrimary cultures of chick osteocytes retain functional gap junctions between osteocytes and between osteocytes and osteoblasts.
The inaccessibility of osteocytes due to their embedment in the calcified bone matrix in vivo has precluded direct demonstration that osteocytes use gap junctions as a means of intercellular communication. In this article, we report successfully isolating primary cultures of osteocytes from chick calvaria, and, using anti-connexin 43 immunocytochemistry, demonstrate gap junction distribution to...
متن کاملIsolation and purification of leaf starch components.
A procedure was developed for the separation and purification of amylose and amylopectin isolated from cotton leaves. Cotton leaves were homogenized in 0.02 molar phosphate buffer at pH 7.0 containing HgCl(2) plus toluene. Crude starch granules were collected by centrifugation and partially purified by treating with acetone and toluene. The starch granules were then dispersed in dimethylsulfoxi...
متن کاملIsolation and purification of primary rodent astrocytes.
Astrocytes are a major cell type in the mammalian central nervous system (CNS). The ability to obtain virtually pure populations of these cells makes it possible to study their function as isolated cells or in mixed populations where they support the growth and survival of surrounding neurons. Unlike other mature CNS cells, mature astrocytes maintain the lifelong ability to reenter the cell cyc...
