The observation by Hafkenscheid (1) thatPhadebas Amylase Test kitswith bovine serum albumin (BSA) gave lower results than those without BSA is, as he infers, evidently caused by differences between the standard curves supplied by the manufacturer. We found rather better agreement for plasma assays between the oldand new-formulation tablets (2). However, we routinely check the calibration curve ...

Novel coronavirus (COVID-19) has been spread in 213 countries and created an emergency situation around the world.A is a group of single-stranded RNA enveloped viruses that causes sever...

Modified 24 Jan 2015; 31 Jan 2015; 19 Feb 2015 This is part of the Turing-inspired Meta-Morphogenesis project, which aims to identify transitions in information-processing since the earliest proto-organisms, in order to provide new understanding of varieties of biological intelligence. Transitions depend on "construction-kits", including the initial "Fundamental Construction Kit" (FCK) based on...

This is part of the Turing-inspired Meta-Morphogenesis project, which aims to identify transitions in information processing since the earliest protoorganisms, in order to provide new understanding of varieties of biological intelligence, including the mathematical intelligence that produced Euclid’s Elements. (Explaining evolution of mathematicians is much harder than explaining evolution of c...

Three widely used commercial hemoglobin electrophoresis kits were studied to ascertain specificity, accuracy, precision, and characteristics of product information. Two hundred and ninety-six hemoglobin samples were used to evaluate each kit. Except for poor separation of hemoglobin F by one kit, all three kits gave generally satisfactory results. We give specific recommendations for improving ...

Introduction: Low-density lipoprotein cholesterol (LDL-C) levels in serum is the basis of diagnosis, classification and management hypercholesterolemia as per current recommendations Adult Treatment Panel III National Cholesterol Education Program. Friedewalds formula used most laboratories to measure LDL-C indirectly. But, not reliable always. Now-a-days, various homogenous assay kits for dire...

Commercially available kits were tested for their ability to detect bacterial and fungal contamination in hydrocarbon fuel systems. The handling ease of the kits was evaluated, and their sensitivity was compared with that of conventional methods. Most kits in both laboratory and field studies compared well with laboratory methods and were sufficiently sensitive to determine contamination in shi...

In this comparative study, three different mutagenesis kits, namely the MutaGene phagemid in vitro mutagenesis kit (Bio-Rad), the Transformerä Site-Directed mutagenesis kit (Clontech) and the Quik-change site-directed mutagenesis kit (Stratagene) were used for the mutagenesis of IPNS genes. However, a large difference in mutation efficiencies among these kits was encountered. Furthermore, these...

Improvement of the methods included in the World Organisation for Animal Health (OIE) Manual of Diagnostic Tests for Aquatic Animals and addition of novel techniques are dependent on the continual development and evaluation of both new and existing methods. Although conventional isolation and characterisation techniques for the diagnosis of many diseases still remain the methods of choice there...

BACKGROUND AND OBJECTIVES This study was conducted by the International Consortium for Blood Safety (ICBS) to identify high-quality test kits for detection of hepatitis B virus (HBV) surface antigen (HBsAg) for the benefit of developing countries. MATERIALS AND METHODS The 70 HBsAg test kits from around the world were evaluated comparatively for their clinical sensitivity, analytical sensitiv...
