Nonliquid Reagent for Detecting Nitrate Reduction

An Improved Reagent for Mycobacterial Nitrate Reductase

A new crystalline reagent for nitrate reductase tests was compared with standard liquid reagents on 437 strains of mycobacteria. The results for isolates of Mycobacterium avium complex, Mycobacterium kansasii, Mycobacterium gordonae, Mycobacterium scrofulaceum, Mycobacterium fortuitum, and Mycobacterium chelonei agreed 100% with the expected results. Of the 177 Mycobacterium tuberculosis isolat...

Detecting long-term drift in reagent lots.

BACKGROUND Between-reagent lot verification is a routine laboratory exercise in which a set of samples is tested in parallel with an existing reagent lot and a candidate reagent lot (before the candidate lot is committed to test patient samples). The exercise aims to verify and maintain consistency in the analytical performance of a test. We examined the limitations of a routine between-reagent...

Monofluor reagent for detecting Chlamydia trachomatis in adolescent outpatients

Chlamydia trachomatis is one of the most prevalent sexually transmitted organisms and is responsible for at least 20% of cases of pelvic inflammatory disease in some patient populations.' Endometritis and salpingitis due to C trachomatis are often referred to as the silent infections. In many instances, the patient does not know that she has an infection until she is evaluated for infertility. ...

The Synthesis of a New Reagent For Detecting Cyanide

This chemical sensor method was selected to detect cyanide in this paper. We synthesized a new reagent which can produce color change from colorless to yellow when encountering cyanide. According to this feature, this reagent can be used to identify cyanide. This reagent had also a good ability of anti-interference, the color change is not obvious when this reagent Encounter the interference io...
