Introduction. Blood, under the form of plasma and serum, is the biofluid of choice for clinical studies in general, particularly as regards metabolomics and lipidomics. 1 Blood can be collected with low invasiveness and is rich in biological information. Blood derivatives contain metabolites as well as lipoproteins secreted by different tissues Plasma is the product of blood that has been prevented from clotting with an anticoagulant. Therefore, You need to use either a serum collection tube or a plasma collection tube, respectively. 1. Serum Tubes. Blood serum is a great (and stable) way of measuring the blood’s proteins, lipids, hormones, electrolytes, etc. The preferred specimen is non-hemolyzed, non-lipemic serum. One study found no significant difference between heparinized plasma and serum, although results from EDTA plasma samples were significantly lower than serum samples. Another study found that different anticoagulants can substantially interfere with myoglobin assays. 1. Blood carry oxygen and carbon dioxide to and from different parts of the body. 2. The blood maintains the body’s temperature. 3. It also transfers nutrients, enzymes, hormones and other molecules to the cells and other parts. 4. It regulates the body’s pH by checking the balance of acid and base. 5. Consistently high blood sugar levels will raise your hemoglobin A1c, and consistently lower blood sugar levels will lower it. However, the two measures aren’t expressed in the same units, which can be confusing. While blood sugar is measured in milligrams per deciliter (mg/dL), hemoglobin A1c is given as a percentage. Summary: 1. Plasma is the part of the blood that contains both the serum and clotting factors. 2. Serum is the part of the blood that remains once the clotting factors like fibrin have been removed. 3. Plasma contains the clotting factors and water, while serum contains proteins like albumin and globulins. Author. Serum albumin is the most abundant circulating plasma protein. It constitutes about half of the total protein content (3.4 to 5.4 g/dL) of the plasma (i.e., component of blood without blood cells). Albumin is a protein synthesized by hepatocytes in the liver and excreted in very high quantities in the blood. Minimal amounts of albumin are also Serum is added as a supplement to culture media at a concentration of 2-10% to provide a mixture of nutritional, hormonal, growth and attachment factors. Serum also acts as a buffer to the cell culture system against a variety of disruptions to cell growth and toxic effects such as pH change, proteoloytic activity, or the presence of heavy Vay Tiền Cấp Tốc Online Cmnd.
