Fig. 4. Isoelectric focusing (IEF) and staining for lactate dehydrogenase (LDH)
activity in crude homogenates of three individual cod (Gadus morhua).
M, white muscle; L, liver; std, lane with pI calibration markers (IEF
3.59.3; Amersham Pharmacia Biotech). Ldh locus classification
(A, B and C) is according to Zietara and Skorkowski
(1993). a/a, a/b and
b/b are Ldh-B phenotypes according to polymorphism in that
locus. For more information, see Table
