Bovine serum albumin (also known as BSA or “Fraction V”) is a serum albumin protein isolated from cows. Rockland produces BSA in various formats for use in immunology, biochemistry, and biotechnology.

What is BSA in biology?
Bovine Serum Albumin (BSA) is supplied with some products to prevent adhesion of the enzyme to reaction tubes and pipette surfaces. BSA also stabilizes some proteins during incubation.
How does BSA stabilize proteins?
The results indicate that BSA stabilized the enzyme by hydrophobic interactions with the heated enzyme and that surface hydrophobicity is a major determinant of the extent of stabilization by a protein.
What is the function of bovine serum albumin?
Bovine Serum Albumin (BSA) is used in a variety of laboratory applications including its function as a protein concentration standard, its function as a cell nutrient and its ability to stabilize enzymes during restriction digest.
What is the purpose of the BSA standards?
The Currency and Foreign Transactions Reporting Act of 1970 (which legislative framework is commonly referred to as the “Bank Secrecy Act” or “BSA”) requires U.S. financial institutions to assist U.S. government agencies to detect and prevent money laundering.
What does BSA stand for in chemistry?
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.
What is BSA and why is it referred to as Fraction V?
How is BSA made? BSA is separated from whole blood using a multi-step fractionation process. His process used these two variables to separate human blood plasma into five fractions, of which the fifth contains mostly albumin. This is why it was called “Fraction V”.
What is BSA in cell culture?
In cell culture, it acts as a small molecule carrier. Because of its negative charge, Bovine Serum Albumin: Binds water, salts, fatty acids, vitamins and hormones and carries these bound components between tissues and cells.
What are three uses of BSA in cell molecular biology?
BSA immunoassay applications include ELISA (Enzyme-Linked Immunosorbent Assay), immunoblots (Western blot and dot blot), and immunocytochemistry (immunohistochemistry and immunofluorescence microscopy). BSA (often from a fetal bovine source) is also used as a nutrient in cell and microbial culture.
What is BSA in blood work?
The serum albumin test looks at the levels of albumin in a person’s blood. If the results indicate an abnormal amount of albumin, it may suggest a problem with the liver or kidneys. It may also indicate that a person has a nutrient deficiency.
Is BSA a dimer?
Analysis of these data indicated that BSA is in a monomer-dimer equilibrium with a dissociation constant of 10 +/- 2 microM at 25 degrees C in 10 mM MOPS-K (pH 5.8).
What is the purpose of using BSA in the Bradford assay?
The Bradford assay responses of the unmodified and reductively methylated proteins are summarized in Fig. 3. Typically, BSA is used as a standard for the Bradford assay, and a calibration curve based on the mass concentration of BSA is used to determine the unknown concentration of a protein.
Why does BSA block?
BSA blocking is a routine practice among clinicians and researchers working on immunoassays throughout the world. The primary role of BSA is to prevent the non-specific binding by blocking the leftover spaces over solid surface after immobilization of a capture biomolecule.
What is a BSA violation?
Isolated and technical violations are those limited instances of noncompliance with the financial record- keeping or reporting requirements of the BSA that occur within an otherwise adequate system of policies, procedures, and processes.
What is required on a CTR?
Filing Obligations A bank must electronically file a Currency Transaction Report (CTR) for each transaction in currency1 (deposit, withdrawal, exchange of currency, or other payment or transfer) of more than $10,000 by, through, or to the bank.
What is a BSA standard curve?
A standard curve is a plot of absorbance vs. a varying amount of some known concentration of protein. Two common proteins used for standard curves are bovine serum albumin (BSA) and an immunoglobin (IgG).
