Fig. 2.

Reference map of the heat-stable proteome of mature Castanospermum australe cotyledons. A 150 μg aliquot of the heat-stable proteins was separated by 2D SDS–PAGE using 24cm non-linear immobilized pH gradient strips (3–10). pI and molecular mass (MW) (in kDa) are indicated. Numbers indicate the polypeptides that were sequenced (see Table 2; and Supplementary Table S3 at JXB online).
