MIICROBIOLOGICAL DETER1\IINATION OF DEOXYRIBoNUCLEIC ACID TITRIMETRIC ESTIMATION OF THYMIDINE SQREN
One of the most sensitive and specific methods for quantitative estimation of deoxyribonucleic acid (DNA) is the microbiological one developed by Hoff-J0rgensen (1951, 1954). This method is l)ased on the fact that Thermobacterium acidophilum (Lactobacillus acidophilus) strain R 26 Orla Jensen is unable to grow in the absence of deoxyribosides. The DNA containing sample is digested with deoxyrib...

متن کاملSimultaneous titrimetric determination of bicarbonate and titratable acid of urine.
An acid-titration method for the determination of bicarljonate and titratable acid in the one sample of urine is described. The method needs only one manipulation of the sample of urine, and was devised to simplify routine laboratory methodology. The accuracy and precision of the urinary bicarbonate method during routine laboratory use is comparable to that obtained by using the Van Slyke manom...
متن کاملThe Titrimetric Determination of “lactobacillus Case1 Factor” and “folic Acid”*
Microbiological tests have aided greatly in the isolation work on “L&o!x~ciZZus casei factor,” demonstrated by Snell and Peterson in 1940 (l), and “folic acid,” the nutrient required by Streptococcus lactis R as defined by Mitchell et al. (2). It seems likely that bacterial assays will continue to play an important role in the study of these compounds, since development of chemical methods has ...
متن کاملAcid-base Titrimetric Assay of Hydroxyzine Dihydrochloride in Pharmaceutical Samples
Two simple titrimetric methods have been developed for the determination of hydroxyzine dihydrochloride (HDH) in pure form and in tablets. The principle of the methods are simple acid-base reactions in which the hydrochloride content of the drug was determined by titrating with an aqueous standardized NaOH solution either visually using phenolphthalein as indicator (method A) or potentiometrica...
