Figure 1.
HSET is expressed as two isoforms in HeLa cells. Total HeLa cell protein was separated by SDS-PAGE and then was blotted with the HSET-specific antibody (αHSET-1) or a COOH-terminal peptide antibody (αCTP-2; Walczak et al. 1997). The two isoforms of HSET detected by αHSET-1 are designated HSET-H and HSET-L. Migration positions of myosin (200), β-galactosidase (116), phosphorylase B (97), and albumin (66) are shown in kD.
