A new chromogenic assay for the specific determination of prothrombin.
A new method for the specific assay of prothrombin is described which utilises Taipan snake venom and the chromogenic substrate Tos-Gly-Pro-Arg-pNA (Chromozym TH). The method is sensitive and reproducible and shows good correlation with a conventional specific assay for prothrombin. The reaction is dependent on calcium ions and phospholipid, and is therefore sensitive to the coumarin-induced pr...
متن کامل[Evaluation of a new chromogenic medium for isolation of MRSA].
Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for an increasing number of serious nosocomial and community-acquired infections, and accurate methods to detect such strains are needed. We tested the susceptibility of 3 kinds of MRSA isolation medium, MRSA Screen Agar, Oxacillin Resistance Screening Agar and CHROMagar MRSA. Both sensitivity and specificity of CHROMagar MRSA we...
متن کاملThe pigments of Micrococcus tetragenus: VI. Micrococcus Tetragenus Infection.
A pattern of variation of Micrococcus tetragenw9 (Reimann, 1936 a, b), the transformation of its bacterial types (Reimann, 1937 a), and the significance of bacterial variation (Reimann, 1937 b,) were described and discussed in a series of papers published in this Journal. A strain of M. tetragenus isolated from the blood of a patient produced white colonies on agar, (Reimann, 1935). During the ...
متن کاملNew chromogenic substrate for determination of serum amylase activity.
A rapid assay for serum amylase activity has been developed based on the use of a new chromogenic substrate-Cibachron Blue-amylose. The procedure requires 0.1 ml of serum and measures the production of soluble chro. mogen, the formation of which islinearwith enzyme activity. Normal human serum has a mean amylase activity of 118 ± 37 (SD) mg dye/100 ml/15 mm or, in international units, 78 ± 24 (...
متن کاملNew developments in chromogenic and fluorogenic culture media.
This review describes some recent developments in chromogenic and fluorogenic culture media in microbiological diagnostic. The detection of beta-D-glucuronidase (GUD) activity for enumeration of Escherichia coli is well known. E. coli O157:H7 strains are usually GUD-negative and do not ferment sorbitol. These characteristics are used in selective media for these organisms and new chromogenic me...
