Description of a new variant in the glutamate-oxaloacetate transaminase system by thin-layer agarose gel isoelectric focusing.

Thin-layer isoelectric focusing in agarose within the pH range of 4.0-6.5 has shown a high resolution of the soluble cytoplasmic glutamate-oxaloacetate transaminase (GOT1) banding pattern. The complex pattern of the common GOT1 phenotype consists of eight bands with different intensities. A genetic variant of GOT1, which has been designated GOT1 Mexico, could tentatively be identified.
