The appts. for separating blood into its different constituents consists of a centrifuge (4), a blood extraction pumps (2, 3) a collector (6) connected to the centrifuge, and detect (8, 9) to control the process. The process is set in operation, when one of the detectors determines ...
Explain why you centrifuge blood samples. What is a PCR reaction, and why is it a useful technique? What is the importance of restriction fragment length polymorphism(RFLP) in diagnostic experiments? Why is a microscope used when studying biology? Why is it importan...
In addition the device enabled the measurement of haematocrit (Hct) and haemoglobin (Kb) to be made since this is the largest blood component determining total protein concentration. A comparison with the centrifuge method revealed an accuracy of +/-2.9 Hct-%, and a comparison with the photo...
Each sample was immediately frozen in a liquid nitrogen container to minimize metabolite degradation. After thawing and centrifugation at 6,000 × g at 4 °C for 15 min, samples were stored in 1.5 mL centrifuge tubes at −80 °C for further analyses. The methods and procedures for ...
The tubes containing the whole blood were allowed to coagulate for a minimum of one hour at room temperature and then placed in a centrifuge and spun at 3000 rpm for fifteen minutes at 4 °C. The resulting serum was removed and divided between two serum tubes to obtain approximately equal ...
A technological gap exists for the iron (Fe) fortification of difficult-to-fortify products, such as wet and acid food products containing polyphenols, with stable and bioavailable Fe. Fe picolinate, a novel food ingredient, was found to be stable over time in this type of matrix. The objecti...
It is currently unclear as to whether sex hormones are significantly affected by soy or whey protein consumption. Additionally, estrogenic signaling may be potentiated via soy protein supplementation due to the presence of phytoestrogenic isoflavones. Limited evidence suggests that whey protein supplementati...
Explain why you centrifuge blood samples. Why haven't sterilization methods been widely adapted to the sterilization of milk? Why is the immediate transport of a clinical specimen required for lab testing? Do you have reason to suspect that they should be...
Plasma was isolated by centrifuging the blood at 5000 rpm for 15 min in the cooling centrifuge. Rats were sacrificed on 61th day by using ethyl ether and liver, kidney, intestine, pancreas were collected and cleaned with 1x PBS and preserved in 10 % formaldehyde for histological studies...
Laboratories receiving samples for vitamin B12 assay in serum separator tubes that have already been centrifuged should either re-centrifuge the tubes, or aliquot and re-centrifuge serum from the tubes prior to vitamin B12 assay.LowreyDepartment of Clinical Biochemistry...
