The globular protein bovine serum albumin (BSA) is a major component of fetal bovine serum. Besides BSA, fetal bovine serum is a rich source of growth and attachment factors, lipids, hormones, nutrients and electrolytes necessary to support cell growth in culture. It is typically added to basal cell culture medium, such as DMEM or RPMI, at a 5 ...
Standard cell culture media commonly consist of a basal medium supplemented with animal serum (such as fetal bovine serum, FBS) as a source of nutrients and other ill-defined factors. The technical disadvantages to using serum include its undefined nature, batch-to-batch variability in composition, and the risk of contamination.
The freeze/thaw cycle causes the platelets to lyse, releasing a large quantity of growth factors necessary for cell expansion. hPL has the highest concentration of growth factors of any serum supplements. [1] FBS-free cell culture media, e.g. with platelet lysate or chemically defined/ animal component free, are used for cell therapy or ...
The growth factors used to supplement media are often derived from the serum of animal blood, such as fetal bovine serum (FBS), bovine calf serum, equine serum, and porcine serum. One complication of these blood-derived ingredients is the potential for contamination of the culture with viruses or prions , particularly in medical biotechnology ...
Conventional methods for growing animal tissue in culture involve the use of fetal bovine serum (FBS). FBS is a blood product extracted from fetal calves. This product supplies cells with nutrients and stimulating growth factors, but is unsustainable and resource-heavy to produce, with large batch-to-batch variation. [21]
The CEA blood test is not reliable for diagnosing cancer or as a screening test for early detection of cancer. [8] Most types of cancer do not result in a high CEA level. [9] Serum from individuals with colorectal carcinoma often has higher levels of CEA than healthy individuals (above approximately 2.5ng/mL). [10]
Bovine serum albumin (BSA or "Fraction V") is a serum albumin protein derived from cows. It is often used as a protein concentration standard in lab experiments. The nickname "Fraction V" refers to albumin being the fifth fraction of the original Edwin Cohn purification methodology that made use of differential solubility characteristics of plasma proteins.
Such convalescent serum is a form of immunotherapy. [citation needed] Serum is also used in protein electrophoresis, due to the lack of fibrinogen which can cause false results. [citation needed] Fetal bovine serum (FBS) is rich in growth factors and is frequently added to growth media used for eukaryotic cell culture.
