BSA (often from a fetal bovine source) is also used as a nutrient in cell and microbial culture. In molecular biology, BSA is used to stabilize some restriction enzymes during digestion of DNA and to prevent adhesion of the enzyme to reaction tubes, pipet tips, and other vessels.

Likewise, people ask, where is bovine serum albumin found?

Bovine Serum Albumin. BSA is a protein found predominantly in the circulatory system of the cow but is also a constituent of the whey component of bovine milk.

How is bovine serum albumin made?

Manufacturing Methods. Bovine serum albumin (BSA) is purified from serum using one of three different purification methods: cold-organic solvent fractionation, heat shock and ion exchange chromatography.

Is bovine serum albumin similar to human albumin?

Bovine albumin-like protein in commercial human albumin for clinical use. The purified proteins showed the same molecular weight as HSA and bovine serum albumin (BSA). By CNBr treatment and trypsin digestion, the purified protein produced the same fragments as BSA.

What are the functions of albumin?

Albumin serves many functions in the body. It is a major component in maintaining COP, platelet function, and normal coagulation and is a free radical scavenger in inflammation. It is an important carrier of drugs, fatty acids, divalent cations (e.g., calcium, zinc), hormones, and bilirubin.

Why is bovine serum albumin used for blocking?

Researchers frequently use bovine serum albumin (BSA) as a blocking agent to prevent non-specific binding of antigens and antibodies to the microtiter well. This work draws attention to the fact that not all BSA preparations are alike.

What is BSA test?

A serum albumin test is a simple blood test that measures the amount of albumin in your blood. If none of those apply to you and you have an abnormal serum albumin level, it may be a sign that your liver or kidneys aren't working correctly. It could also mean that you have a nutritional deficiency.

What is a BSA standard curve?

A standard curve was developed using a series of Bovine Serum Albumin (BSA) standards in the 100 μg/ml to 1,500 μg/ml range. The absorbance of each sample was measured at 595 nm and plotted versus [BSA]. Alternatively, the sample could be concentrated several fold, thereby allowing the lower sample volume to be used.

What is a BSA standard?

The Bovine Serum Albumin Standard
Bovine serum albumin (BSA) is a globular protein that is often used as a protein concentration standard in lab experiments as well as in numerous other biochemical applications.

What is a bovine?

Bovine comes from the Latin word for "cow", though the biological family called the Bovidae actually includes not only cows and oxen but also goats, sheep, bison, and buffalo. So bovine is often used technically, when discussing "bovine diseases", "bovine anatomy", and so on.

What is bovine blood?

INTRODUCTION. Bovine blood is made up of 80.9% water, 17.3% protein, 0.23% fat, 0.07% carbohydrate, and 0.62% minerals (Alencar, 1983). Blood composition is similar to meat composition except for the iron (36.3 mg/100 g of blood), which is ∼10 times the concentration in meat (Wismer-Pedersen, 1979; Alencar, 1983).

What is BSA stored in?

Lyophilized BSA although stable at room temperature for 3 weeks, should be stored 2-8°C. Upon reconstitution BSA should be stored at 4°C between 2-7 days and for future use below -18°C.

Is Bovine Serum Albumin hydrophobic?

We studied the adsorption of bovine serum albumin (BSA) from phosphate-buffered saline (pH 7.4) to hydrophilic and hydrophobic surfaces. The BSA molecules adsorbed to the hydrophilic surface with a higher interaction strength than to the hydrophobic surface.

Does BSA expire?

To effectively preserve the integrity of BSA, it should be stored at the recommended temperature and protected from light. For stability and optimal performance, this product should be stored at 2 to 8 C. Do not use after the expiration date. Lyophilized powder should be free flowing.
