Cell Surface Oligonucleotide-Binding Proteins of Human Squamous Carcinoma A431 Cells

Abstract

Affinity modified with Flu-DAP-p(N)₁₆degU oligonucleotide-binding proteins were isolated by affinity chromatography using Ultrogel A2 - anti fluorescein antibodies. After separation by SDS-PAGE the proteins with molecular masses about 68 kDa were MS/MS sequenced and identified as keratin K1, keratin K10, keratin K2e and albumin.
