परख-का इसके अंग्रेजी अर्थ का उदाहरण

Other examples include assays for testing vancomycin resistance genes vanA and vanB in Enteroccocus species, and antibiotic resistance in Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli.

Such assays do not require much fluid to be tested, are rapid and portable.

If, on the other hand, one is interested in the association between gene expression and breast cancer incidence, it would be very expensive and possibly wasteful of precious blood specimen to assay all 89,000 women without breast cancer.

In this situation, one may choose to assay all of the cases, and also, for each case, select a certain number of women to assay from the risk set of participants who have not yet failed (i.

Exposure is defined prior to disease development based on data collected at baseline or on assays conducted in biological samples collected at baseline.

The assay relies on the use of terminal deoxynucleotidyl transferase (TdT), an enzyme that catalyzes attachment of deoxynucleotides, tagged with a fluorochrome or another marker, to 3'-hydroxyl termini of DNA double strand breaks.

The fluorochrome-based TUNEL assay applicable for flow cytometry, combining the detection of DNA strand breaks with respect to the cell cycle-phase position, was originally developed by Gorczyca et al.

Concurrently, the avidin-peroxidase labeling assay applicable for light absorption microscope was described by Gavrieli et al.

However, for years there has been a debate about its accuracy, due to problems in the original assay which caused necrotic cells to be inappropriately labeled as apoptotic.

Based on several defective radiocarbon assays, in 2009 Yule rejected his low chronology published in the final report of 2001.

Quenching is the basis for Förster resonance energy transfer (FRET) assays.

Historically, thromboplastin was a lab reagent, usually derived from placental sources, used to assay prothrombin times (PT time).

If some doubt remains regarding the diagnosis, definitive diagnosis can involve osmotic fragility testing, an autohaemolysis test, and direct protein assaying by gel electrophoresis.
