Abstract

The present invention relates to immunoglobulin-binding artificial proteins (repetitively linked-proteins) which result when either one of or several numbers of the IgG-binding domains in protein A molecule is defined as a unit, and repetitive multiple links are made thereof. These repetitive proteins exhibit a superior ability for IgG purification to naturally occurring protein A, and the mixture of these repetitive proteins may be used as excellent molecular weight markers.
