Comparison of four commercially available cAMP kits.
In this study four commercially available cAMP kits were compared and shown to differ with respect to reliability, sensitivity, simplicity and expiration time. It is not possible to recommend a particular kit, because the choice depends on the demands of the investigator, which, of course, may vary. However, in our opinion, one of the kits was inferior to the others.
متن کاملCatecholamine interference with enzymatic determination of nonesterified fatty acids in two commercially available test kits.
We present evidence that catecholamines, which are commonly used to stimulate lipolysis in adipose tissue in vitro, interfere with the enzymatic determination of non-esterified fatty acid (NEFA) in two commercially available kits. Measurement of a 100 mumol/L standard with the Wako "NEFA C" test kit was 60% inhibited by 100 mumol/L norepinephrine and was completely inhibited by 100 mumol/L isop...

متن کاملDevelopment of qRT-PCR Test for Quantification of Rubella Virus in Commercially Available Vaccines
vaccines is considered as a critical point and in-process of quality control (IPQC) test of vaccine production. Rapid tests, like real time PCR, are more appropriated when the production occurs at industrial scale because of the amounts of starting materials and the excess of consumed time required. In the current study, a real-time quantitative reverse transcription-polymerase chain reaction...
متن کاملAccuracy of commercially available residential histories for epidemiologic studies.
A key problem facing epidemiologists who wish to account for residential mobility in their analyses is the cost and difficulty of obtaining residential histories. Commercial residential history data of acceptable accuracy, cost, and coverage would be of great value. The present research evaluated the accuracy of residential histories from LexisNexis, Inc. The authors chose LexisNexis because th...
