10X PBS MaxTag™ Histo for IHC

Description

Background

Phosphate Buffered Saline (PBS) is a regularly used buffer in biological research. The phosphate ions help maintain a constant pH around neutral. The osmolarity of solution typically matches that of the human body (isotonic solution). PBS can act as a diluent for many experimental preparations and is non-toxic to cells. This preparation contains 0.1% sodium azide as a preservative and is 10X concentrated to be diluted 10-fold to the working concentration.

Application Note

10X PBS pH 7.2 with Azide (0.2 M Potassium Phosphate 1.5 M Sodium Chloride 0.1% (w/v) Sodium Azide) is a concentrated stock solution and should be diluted appropriately with distilled, deionized water or equivalent to its final working concentration. This buffer consists of 0.2 M Potassium Phosphate, 1.5 M Sodium Chloride and 0.1% (w/v) Sodium Azide at a pH of 7.2. 10X PBS pH 7.2 with Azide (0.2 M Potassium Phosphate 1.5 M Sodium Chloride 0.1% (w/v) Sodium Azide) is meticulously prepared using ultra pure reagents dissolved in highly polished pharmaceutical grade deionized water.

Purity/Specificity

10X PBS pH 7.2 with Azide (0.2 M Potassium Phosphate 1.5 M Sodium Chloride 0.1% (w/v) Sodium Azide) was aseptically filtered through a Millipore 0.22 micron filter into clean, pre-sterilized containers. 10X PBS pH 7.2 with Azide (0.2 M Potassium Phosphate 1.5 M Sodium Chloride 0.1% (w/v) Sodium Azide) was tested on trypticase soy agar for 24 hours, 48 hours and 72 hours and was found to be negative for bacteria.
