Four methods are recommended:

1.   Special Cereal Typing Kit “Sortype” uses cathodal nativ electrophoresis pH 4.3:
For determination of wheat- and barley-varieties via their Prolamins (Gliadins), incl. malt, see below.
Also suitable for millet- rice- and maize-varieties
Malt-Method: A special extraction procedure is necessary for the malt-grains. Go to “Malt Method”
All sample treatments, see manual: Cereal typing with the Sortype Kit
2.   Protein Buffer Kit Cathodal and DryGel Elpho 12.5% 52S: uses native cathodal electrophoresis pH 5.5
For determination of wheat- and barley-varieties. Manual: Protein Buffer Kit Cathodic
3.  IEFGel cereal 24S EQ-type, IEFGel cereal 40S EQ-type or IEFGel 104S cereal bidirect EQ-type
Produced w
ith special SepaLytes Wheat (ProTec Heidelberg)
For determination of wheat- (and barley) -varieties
Manual: DryGel IEF cereal
4.   SDSGel 12.5% 40S EQ-type
Suitable also for determination of baking quality
ElphoGel Kit SDS
