Growth Characteristics of Poliovirus in Hela Cells: Nucleic Acid Metabolism
The RNA and DNA contents of the nucleus and cytoplasm of the HeLa cell were determined. The rates of incorporation of P(32) into the various nucleic acid fractions were established for the ordinary HeLa cell maintained under a set of standard conditions. The changes in the rates of incorporation of P(32) and in the amounts of RNA and DNA which occurred subsequent to infection with poliovirus we...
متن کاملColorimetric Estimation of Indoleacetic Acid.
The wide use of the auxin, indoleacetic acid, in physiological and biochemical experiments has promoted interest in methods for its colorimetric estimation. MITCHELL and BRUNSTETTER (1) have proposed both the nitrite and the ferric chloride-sulphuric acid tests for the quantitative estimation of indoleacetic acid (IAA) in aqueous solutions, basing their suggested procedures upon a study of opti...
متن کاملResponses of Avena coleoptiles to suboptimal fusicoccin: kinetics and comparisons with indoleacetic Acid.
Proton excretion induced by optimal concentrations of indoleacetic acid (IAA) and fusicoccin (FC) differs not only in maximum rate of acidification but also in the lag before onset of H(+) excretion and in sensitivity to cycloheximide. Because these differences might simply be a consequence of the difference in rate of proton excretion, FC and IAA have now been compared using oat coleoptiles (c...
متن کاملHyaluronic-Acid Mediated Adhesion of Pasteurella multocida to HeLa Cells
Adhesion of bacteria to host cells is a crucial step in colonisation and disease pathogenesis. In this connection, further studies were conducted to analyse the attachment mechanisms of Pasteurella multocida to HeLa cells. Of 10 strains of P. multocida, belonging to serotypes A, B, D and E, all six of serotype A strains adhered strongly to HeLa cells. Exposure of the six strains to several phys...
متن کاملPromotion of indoleacetic Acid oxidase isoenzymes in tobacco callus cultures by indoleacetic Acid.
Indoleacetic acid oxidase in tobacco callus cultures (Nicotiana tabacum L., cv. White Gold) was composed of at least two groups of isoenzymes, which were distinctly different in electrophoretic mobilities and in responses to growth substances. Indoleacetic acid had dual effects; at low concentrations it promoted the development of two fast-migrating indoleacetic acid oxidase isoenzymes, but at ...
