Abstract

The process involves prodn of gelatin gel treated with transverse crosslinked reagents comprising dialdehydes; extrusion of the prod. through a sieve with opening of size e.g. 200-250 microns, treatment of the obtd. particles with a 0.25-0.75% soln. of proteolytic enzyme of animal origin using vol. ratio of enzyme soln to gel of 0.75-1.25:1; secondary treatment with dialdehydes; and finally addn. of reducing agents. USE/ADVANTAGE - In microbiological for culturing surface-dependent animal cells. - The prepd. micro-carrier is obtd. in higher yield and has improved quality. - (5pp Dwg.No.0/0)

Description

(57) Řešení ae týká oblasti biologie a mikrobiologiokého průmyslu, zejména pěstování povrchově závislých Živočišných buněk. Za účelem zvýšení výtěžku a zlepšení kvality výsledného produktu se částice gelu zpraoovávají 0,25 až 0,75 %ním roztokem proteolytického enzymu živočišného původu při objemových vzájemných poměrech roztoku enzymu k želatinověrnu gelu 0,75 až 1,25 : 1» a před přidáním redukčních Činidel se provádí druhotné zpracování dialdehydy.(57) The solution ae concerns the field of biology and the microbiological industry, in particular the cultivation of surface-dependent animal cells. In order to increase the yield and improve the quality of the final product, the gel particles are treated with a 0.25-0.75% solution of animal proteolytic enzyme at a volume ratio of enzyme solution to gel gelatin gel of 0.75-1.25: 1 and prior to the addition of reducing agents. The agents are subjected to secondary treatment with dialdehydes.
