“…While some authors reported that RAbs showed lower 530 affinity than its parental MAb (Kramer & Hock, 1996;Graham, Porter, & Harris, 1995;Choi et al, 2004), i.e. the same behaviour as we found, others reported a comparable (Tout, Yau, Trevors, Lee, & Hall, 2001;Alcocer, Doyen, Lee, & Morgan, 2000;Nishi, Ishiuchi, Morimune, & Ohkawa, 2005) or even higher (Alcocer, Doyen, Lee, & Morgan, 2000;Strachan, Grant, Learmonth, Longstaff, Porter, & Harris, 1998;Pan et 535 al., 2006) affinity of RAbs over their counterpart MAbs. Results obtained in this study and those reported in the literature suggest that the folding of each scFv and, therefore, their analyte interaction properties depend on its particular amino acid sequence.…”

“…This is a popular technique as it can provide a wealth of information about the interaction of the antibodies with the analyte, in addition to having the potential to be the basis of an immunosensor technique. There are many research groups investigating pesticides with SPR transduction [43][44][45][46]. Keay and McNeil [47] used an amperometric immunosensor to determine atrazine.…”

“…Pan et al (2006) desarrollaron ELISAs de clembuterol basados en anticuerpos recombinantes, con un valor de I 50 (0.78 ng/ml) del mismo orden aunque ligeramente inferior al del ELISA basado en el anticuerpo monoclonal (1.34 ng/ml). Finalmente, Strachan et al (1998) obtuvieron un anticuerpo recombinante frente a atrazina con una afinidad hacia el analito 6 veces superior a la del anticuerpo monoclonal.…”

“…Estos valores mejoraron los obtenidos con el anticuerpo monoclonal de referencia, aunque en este caso, la afinidad del monoclonal por el analito era realmente baja (el valor de la I 50 del inmunoensayo era de 180 µg/ml). Por otro lado, Charlton et al (2001) llevaron a cabo ELISAs de atrazina con fragmentos scFv obtenidos a partir de linfocitos de ovejas inmunizadas, que mostraron una afinidad mayor que los realizados por Strachan et al (1998) con AcRbs obtenidos a partir de hibridomas. Por último, Finlay et al (2006) describieron la obtención de anticuerpos recombinantes de alta afinidad frente al ácido domoico a partir de pollos inmunizados.…”
