Phosphate Buffered Saline (PBS)

Product Information

Phosphate Buffer saline is a water-salt, buffer solution used to maintain a constant pH during biological and chemical applications as well as tissue processing. It contains disodium hydrogen phosphate, sodium chloride. The pH of standard and custom PBS formulations ranges from 7-7.4 when the buffer is ready to use.
PBS from BIOLOGOS is available in 1x or 10x concentrations, with or without calcium and magnesium, as well as custom formulations.

Q:

What Is the Difference Between PBS, Phosphate Buffer, and DPBS? Is There a Difference?

A:

Phosphate Buffer Solution = Phosphate Buffer. Both PBS & DPBS have uses in maintaining pH constants, as well as irrigation or transport use in tissue processing. Dulbecco’s differs with a range of concentrations (ex. 1X, 10X), and additives, such as Calcium and Magnesium.

PBS and DPBS can often be used interchangeably because they provide the same functions and have similar composition; however, DPBS has a lower concentration of phosphate.

Q:

What Are Common PBS Composition / Modifications?

A:

Basic Phosphate Buffered Saline, or PBS consists of sodium chloride and disodium hydrogen phosphate. Common additives are potassium chloride or potassium phosphate. PBS from Biologos is available in 1x or 10x concentrations, with or without calcium and magnesium, as well as, custom formulations and custom pH levels.

Biologos makes each PBS formulation upon request. After your order is placed, we will stock and store your custom PBS formulations in our GMP certified facility and ship your formulation as you request it- ensuring product quality.

Q:

What Are the Formulation Options? What Can Be Added to the Base Formula?

A:

Biologos manufactures three standard formulizations of phosphate buffer solution, each with a different monobasic & dibasic sodium phosphate solution mix, all of which are commonly used in tissue recovery. Further custom formulizations, typically using potassium chloride and/or potassium dihydrogen phosphate, are also available.

Q:

Why Do We Wash Cells With PBS?

A:

As PBS’ osmolarity and ion concentrations closely match the human body, PBS is non-toxic to cells.

Q:

How Do You Handle PBS?

A:

When handling all biological products, it is a best practice to use industrial hygiene standards and aseptic handling techniques. If PBS comes in contact with the eye, irritation is likely.

Q:

How Do You Store and Transport PBS? What Is the Normal Shelf Life?

A:

Phosphate Buffered Saline is supplied in gamma-irradiated, sterile PETG or PETE bottles. We recommend that PBS solution be stored at ambient temperatures.

When transporting, PBS is shipped ambient by less than truck-load carrier or overnight, as needed.

The shelf life of phosphate-buffered saline is of 2 years when stored properly.

Q:

What Are the Uses of PBS?

A:

PBS is mostly commonly used as buffer solution in biological and chemical applications, but can be formulated with additives for use in other applications, such as:

  • A diluent for concentrated substances
  • A rinsing agent, for containers with cells
  • Separating clumped cells (PBS with EDTA)
Q:

What Are the Different Varieties of PBS, if Any?

A:

Phosphate Buffer solution is manufactured with a R.O.D.I water and USP grade sodium phosphate solutions. The concentration of R.O.D.I water, monobasic & dibasic solutions can be customized as desired by customer.

Q:

What is PBS/ PBS Biology?

A:

Phosphate Buffered Saline, PBS, is a water-based salt solution containing sodium chloride and sodium phosphate. PBS is commonly formulated to help cells maintain a constant pH and osmosis but can be modified for use in other applications related to biological research.
