Researchers often purify DNA from blood samples prior to performing PCR because it is believed that blood constituents and the reagents commonly used to preserve blood samples (e.g., anticoagulants) interfere with PCR. In order to save the time and expense required for template purification, several methods have been reported for direct PCR of blood samples. These include microwave irradiation,...

The purpose of this paper 2 is to present the results of experimental work on the preservation of whole blood in vivo and in vitro carried out over a period of several years. Certain standards of preservation in vitro (the osmotic resistance) and in vivo (the serum bilirubin variations) have been carried out extensively in the early as well as in the late experiments, thus affording a means of ...

background: the study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. this work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. the applied shear rate was from 12 to 375 s-1. low shear viscosity (up to 100 s-1) depends mainly on the erythrocytes ag...

background brucellosis is the most common global zoonosis and an important public health problem in many parts of the world including iran. diagnosis of brucellosis is frequently difficult to establish and conventional methods are not always successful in identifying the organisms. rapid detection of brucella species by an automated blood culture system and polymerase chain reaction (pcr) may l...
