This invention relates to amino acid sequences from within a consensus peptide of the formula: VEKNITVTASVDPTIDLLQADGSALPSAVALTYSPA (Seq. #1). Eight mer peptides from within the consensus peptide were tested against an antibody raised to the consensus peptide. Studies relating to antibody raised to denatured proteins from the natural organisms producing the family of proteins were also useful and showed particular value of some sequences. A sequence of the formula ASVDPTIDLLQA (Seq. #2) was identified thereby. An enlarge sequence of the formula TVTASVDPTIDLLQAD (Seq. #3) is also especially interesting as are intermediate sequences such as sequences VTASVDPTIDLLQAD (Seq. #4), TASVDPTIDLLQAD (Seq. #5), and TASVDPTIDLLQA (Seq. #6) as being binding sites for antibodies raised to the denatured proteins.
L'invention concerne des séquences d'acides aminés provenant d'un peptide consensus de la formule: VEKNITVTASVDPTIDLLQADGSALPSAVALTYSPA (Séq. #1). On a essayé huit peptides mer provenant du peptide consensus et dirigés contre un anticorps dirigé contre le peptide consensus. Des études relatives à un anticorps dirigé contre des protéines dénaturées, provenant d'organismes naturels produisant la famille de protéines, ont été également utiles et ont montré la valeur particulière de certaines séquences. On a identifié ainsi une séquence de la formule ASVDPTIDLLQA (Séq. #2). Une séquence agrandie de la formule TVTASVDPTIDLLQAD (Séq. #3) s'est révélée particulièrement intéressante, de même que des séquences intermédiaires, telles que VTASVDPTIDLLQAD (Séq. #4), TASVDPTIDLLQAD (Séq. #5), et TASVDPTIDLLQA (Séq. #6), car elles constituent des sites de fixation d'anticorps dirigés contre les protéines dénaturées.
