01 Description, applications & specifications
Gamborg B5 medium by Duchefa Biochemie is supplied for plant tissue culture and laboratory research.
Description and application
B5 medium has been defined for the growth of cell suspensions of soybean root cells in the presence of 2,4 D. Nitrate was required in a concentration of 20-30 mM. An addition of 2 mM ammoniumsulphate led to an increase in cellgrowth. NH4+ when added as the sole source of nitrogen, did not support growth. Similar results were obtai-ned when NH4NO3 was substi-tuted for (NH4)2SO4. However, ammonium ions depressed growth when the concen-tration excee-ded 2 mM. Variati-ons in the concentrations of phosphate, calcium and magnesi-um resulted in relatively minor chan-ges in growth rate. Thiamine is known to be an essenti-al nutrient for cell growth and is increa-sed in concentrati-on up to 10 mg/l.
