Fig. 1From: Royal jelly-derived proteins enhance proliferation and migration of human epidermal keratinocytes in an in vitro scratch wound modelIsolation of proteins from royal jelly. a Fractionation of royal jelly water-soluble proteins using an ÄKTA™pure system. The elution positions/retention times of Fractions 1 and 2 are indicated. b SDS-PAGE analysis of the protein content of the collected fractions. Lane 1 and lane 2 are the proteins in Fractions 1 and 2, respectively. M represents molecular weight protein standardBack to article page
