MS low iron

Murashige & Skoog 1µM iron medium

MS 10x micronutrients is 100 µM FeSO4, so MS complete is 10 µM

FeSO4 stock is 10 mM, which is 10,000x 1 µM

add: mL ferrous sulfate 10 mM
add: mL KI 10,000X
add: mL manganese sulfate 1000X
add: mL moybdic acid 10,000X
add: mL zinc sulfate 1000X
add: g MES, pH to 5.7 with KOH
bring to mL final volume
add: g bacto- or phyto-agar
autoclave for minutes
