antibodies against integrins are disclosed , as are methods of making same . such antibodies are elicited by immunizing with synthetic peptides corresponding to the cytoplasmic domains , or functional portions thereof , of various integrin subunits . peptides employed for such immunization include known cytoplasmic domain amino acid sequences for integrin subunits , as well as newly discovered cytoplasmic domain amino acid sequences for integrin subunits . the latter amino acid sequences are also disclosed and described herein .
