Pectolyase Y-23 (A. japonicus)
Pectolyase Y-23 is a highly purified maceration enzyme from Aspergillus japonicus. It contains two types of pectinase such as endopolygalacturonase and endo-pectin lyase in high activity. Included is a maceration stimulating factor which stimulates tissue maceration by both pectinases.
Unit Definition: One unit is defined as an increase in A235 by 1.0 in the reaction mixture per minute.

Phenol red, 0.5% solution, 100 mL
Phenol red is an acid-base indicator. It is made by condensing two moles of phenol with one mole of o-sulfobenzoic acid anhydride. Phenol red in tissue culture media can act as a weak estrogen, especially with human breast cancer cells. Phenol red can be used to measure hydrogen peroxide in cultured macrophages in multiwell plates.

Phosphate Buffered Saline (PBS) (1X ) Dulbecco’s formula w/o Ca, Mg
Balanced salt solution (BSS) used for the handling and culturing of mammalian cells
Used to irrigate, wash, and dilute mammalian cells
Provides a buffering system to maintain the medium within the physiological pH range (7.2 – 7.6) -
Phosphate Buffered Saline (PBS), Dulbecco’s formula, powder, w/o Ca, Mg
Phosphate Buffered Salts, Dulbecco’s Formula (DPBS) is a balanced salt solution (BSS) used for the handling and culturing of mammalian cells. DPBS is used to irrigate, wash, and dilute mammalian cells. Phosphate buffering maintains the pH in the physiological range. Calcium and magnesium facilitate cell binding and clumping. DPBS without these ions can be used to wash and rinse suspended cells.
