Why do you need a cassette or a slide printer?Release date：2017-11-16

Why do you need a cassette or slide printer??   Surgery specimens are the most important researching materials and the most valuable first-hand diagnostic materials.The procedure of surgery specimens that are sent to the pathology department and received without mistakes,well fixed and stored is a first important part to ensure good pathology section and correct diagnosis.   In traditional batch processing，technicians have to label manually hundreds of specimens...

The IVD Industry TodayRelease date：2017-07-20

BOB会员By Harry Glorikian The field of in vitro diagnostics is going through a period of rapid growth and innovation. Rising healthcare costs have led to a greater emphasis on evidence-based medicine and a focus on improved patient outcomes. An aging population along with the growing epidemic of chronic diseases and some infectious diseases are creating a demand for diagnostic devices for a variety of conditions. Development of these devices is challenging. Regulation of IVDs in the U.S. largely fal...

New way cells turn off genesRelease date：2017-07-20

BOB会员 A microscopy image of the complete set of chromosomes in a 2-cell stage mouse embryo reveals chemical tags that ,decorate, DNA-packaging proteins called histones. The tag H3K27me3 (shown in green), can switch gene activity off. The tag H3K4me3 (shown in red) can turn gene activity on. White represents the chromosomes' centromeres, and blue represents DNA. Credit: Azusa Inoue and Yi Zhang Cells have more than one trick up their sleeve for controlling certain genes that regulate...

The role of POCT and rapid testingRelease date：2017-07-04

By: Jeffrey A. DuBois    Point-of-care testing (POCT) is defined as medical testing at or near the site of patient care.1-3 The first reported use of POCT is found in papyrus documents dating back to 1550 B.C., which depict Egyptian physicians using ants to determine glycosuria in patients suspected of having diabetes mellitus. Today, as it was then, the goal of POCT is to provide immediate, convenient, and easy-to-use diagnostic testing that shortens the therapeutic turnaround time w...

Principle of immunofluorescenceRelease date：2017-07-20

BOB会员 Immunofluorescence is an assay which is used primarily on biological samples and is classically defined as a procedure to detect antigens in cellular contexts using antibodies. The specificity of antibodies to their antigen is the base for immunofluorescence. The biological samples include tissue and cells. Immunofluorescence allows researchers to evaluate whether or not cells in a particular sample express the antigen in question. In cases where an immunopositive si...
