Fibrin strands form when fibrinogen is converted into fibrin by the enzyme thrombin during the blood clotting process. Thrombin acts on fibrinogen to create fibrin monomers, which then polymerize into a network of fibrin strands that help to trap platelets and form a stable blood clot.

What arrangement of atoms in a repeating pattern in a mineral causes the formation of?

The arrangement of atoms in a mineral sample can cause the formation of crystals.


How do you assay thrombin potency?

You can assay thrombin potency by measuring its ability to convert fibrinogen to fibrin, typically using a chromogenic or clot-based assay. The results are compared to a standard curve to determine the potency of the thrombin sample.


Isopropyl alcohol causes DNA to do what?

Isopropyl alcohol can cause DNA strands to precipitate out of a solution, essentially forming a visible clump of genetic material. This property is used in DNA extraction techniques to isolate DNA from a sample by adding isopropyl alcohol to the solution, causing the DNA to become visible and separate from other cellular components.


What is the purpose of adding isopropyl alcohol to your sample of DNA?

Isopropyl alcohol is added to DNA samples to precipitate the DNA, facilitating its separation from the aqueous solution. When isopropyl alcohol is mixed with a DNA solution, it causes the DNA to become less soluble, allowing it to clump together and form visible strands. This process enhances the yield and purity of the isolated DNA, making it easier to extract for further analysis or experimentation.


What causes the reaction in chromatography?

In chromatography, the reaction is caused by the interaction between the molecules of the sample being separated and the stationary phase (such as paper or silica gel). This interaction leads to different components of the sample moving at different rates, resulting in separation based on their affinity for the stationary phase.

What is D Dimer?

When a blood clot is broken up within the human body, it releases fibrin (the protein which causes clotting to occur). A D-dimer level measures the amount of fibrin within a blood sample (where the fibrin will float around), to help determine if a clot has been present.


How many full-length strands of hair are collected from the scalp to use as a sample?

Most testing facilities collect between 90 to 120 strands of hair that is taken from the scalp to use as a sample. A 1.5 inch hair sample can detect up to 90 days prior to the date of the test.

Why purple colour give in Molisch test?

The purple color in the Molisch test is due to the formation of a complex between the carbohydrate present in the sample and the alpha-naphthol reagent used in the test. This complex formation indicates the presence of carbohydrates in the sample.

What are the three PCR stages?

The three stages of PCR (polymerase chain reaction) are denaturation, annealing, and extension. In denaturation, the DNA sample is heated to separate the double-stranded DNA into two single strands. In the annealing step, primers bind to the DNA strands. Finally, in the extension step, DNA polymerase adds nucleotides to the primers, synthesizing new DNA strands.


How can one test for protein in a sample?

One can test for protein in a sample by using a method called the Biuret test. This test involves adding a reagent to the sample, which causes a color change if protein is present. The intensity of the color change can indicate the amount of protein in the sample.

What element is responsible for the formation of cloudy solution in the silver nitrate test?

The formation of a cloudy solution in the silver nitrate test is a result of the precipitation of silver chloride when it reacts with chloride ions in the sample. Silver chloride is insoluble in water, leading to the formation of a cloudy appearance in the solution.
