VITRO AGAR

 

DESCRIPTION

Agar is a natural hydrocolloid extracted from several species of red algae, mainly the Gelidium, Gracilaria and Pterocladia types. This agar was developed especially for in vitro cell culture. Due to its physical-chemical characteristics (color, transparency, degree of purity) and, above all, its high gel strength (approximately 1000 g/cm2, which allows usage levels as low as 0.4 – 0.5%), this agar is recommended for micro propagation techniques (initiation, propagation, radiation, etc.). This product is strictly controlled and designed to give high yields in large industrial operations for growing tissue culture plants (ornamentals, horticulture, woody plants, etc.).
