Use of hydrogen peroxide-egg albumin to eliminate nonspecific staining in immunoperoxidase techniques.

The application of hydrogen peroxide and egg albumin to paraffin sections before immunostaining prevents nonspecific staining by immunoperoxidase techniques. This method is more effective than pretreating secions with normal sera, or using either egg albumin or hydrogen peroxide separately, or using diluted antisera with prolonged incuabations in the staining procedure.
