A convenient and rapid procedure has been developed to extract RNA polymerase II quantitatively from cultured mammalian cells. The procedure was successfully employed on HeLa, CHO, L, and MDBK cells. The easy extraction of RNA polymerase II by freeze-thaw of cells in a buffer of low ionic strength s

โฆ Synopsis
A method is described for the separation and assay of radiolabeled glycosaminoglycuronans (GAGS) from cell culture medium. Following papain digestion and precipitation with cetylpyridinium chloride onto cellulose ester filter membrane, hyaluronic acid can be separated from sulfated GAGS by selective elution with HCI.

A simple and rapid methodology for the preparation of single-cell suspension from animal tissues is described. It uses a device called a "tissue press" to mince the tissue into small pieces of desired sizes which are then dissociated into single cells using a pipette. The device is inexpensive and t
A simple, rapid, and sensitive method for the measurement of DNA, RNA, and protein synthesis in cell samples is presented. Tke method measures the amount of isotope incorporated into these macromolecules after cell collection on filter paper and washing with a methanol:chloroform:water mixture. Samp
