BSA Stock Solution. MACS BSA Stock Solution is used for the fast and easy preparation of a preservative-free standard MACS Separation Buffer that is suitable for any MACS Cell Separation System. The MACS® BSA Stock Solution consists of phosphate-buffered saline supplemented with 10% bovine serum albumin.
What is BSA solution used for?
The MACS® BSA Stock Solution consists of phosphate-buffered saline supplemented with 10% bovine serum albumin. By simply diluting it 1:20 with the autoMACS® Rinsing Solution an optimal buffer for cell preparation and separation of magnetically labeled cells is obtained.
What is the Macs® BSA stock solution?
Feb 04, 2020 · What is BSA solution? Bovine serum albumin (also known as BSA or "Fraction V") is a serum albumin protein isolated from cows. 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.
How do you make a 1% BSA solution?
Bovine serum albumin (BSA) For a 10% (100 mg/mL) stock solution of BSA, dissolve 1 g powdered Fraction V or molecular biology grade BSA in 10 mL of distilled H 2 O; to avoid clumping, dissolve by layering the powder on the surface of the liquid. Gently rock the capped tube until the BSA has dissolved completely. Do not stir.
What is the concentration of BSA in 1ml solution?
Dec 02, 2010 · Well to make 30% stock solution of BSA from powder form you need to dissolve 30g of BSA into 100ml of solvent (water). Thus dissolved solution becomes 30% (w/v) stock solution. How will you prepare...

How long does BSA last in solution?
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.
How do you make a solution?
The following steps describe the procedure for making a solution of a specific molarity from a pure, solid substance. First, weigh out the correct mass of solute. Dissolve the solute in water, keeping the volume less than the desired total volume of solution. Dilute the solution to the desired total volume of solution.
Do you need to wash after blocking?
Sufficient washing after the blocking step is usually performed in order to remove excess protein that may prevent detection of the target antigen. However, many researchers do not wash after the blocking step because they dilute their primary antibodies in their blocking buffer.
Is BSA stable in water?
SOLUBILITY / SOLUTION STABILITY: Albumins are readily soluble in water and can only be precipitated by high concentrations of neutral salts such as ammonium sulfate. The solution stability of BSA is very good (especially if the solutions are stored as frozen aliquots).
Does BSA go bad?
HELP– Is BSA (Bovine Serum Albumin) stable at room temperature? The powder will be fine. It's much more important to keep it dry than to keep it cold. When it goes bad, it simply won't dissolve.
How do you dissolve BSA in water?
The best procedure for dissolving BSA is to “wet” the solution by layering it. This should begin by adding a layer of BSA into the mixing vessel followed by the water or buffer solution.
How do you dilute BSA standards?
Prepare BSA Standard working solution to 200 µg/ml by diluting 0.5 ml of BSA Standard in 4.5 ml of de-ionized water or the diluent.

What is stock solution?
posted on February 10, 2019. A stock or standard solution is a solution in which you accurately know its concentration. You can make stock solutions in the chemistry laboratory or buy from chemical manufacturers. Once you have a stock solution, you can prepare solutions of lower concentration by diluting the concentrated stock solution.
What does it mean to dilute a solution?
To dilute means to add a certain amount of solvent (water) to a certain amount of concentrated stock solution. If you add a certain amount of solvent to a certain amount of concentrated stock solution, you will notice that the amount of solute present in the stock solution is the same amount present in the dilute solution.
Is sulfuric acid more dense than water?
As you may know, sulfuric acid is much denser than water, so as you add it to water, its molecules are able to travel within and mix well with the water molecules. However, because water is less dense than sulfuric acid, if you add it to sulfuric acid, its molecules will create a barrier in which you have water on top and sulfuric acid below.
