Animals were immunized with a synthetic polypeptide with the sequence LWEIATYGMSPYPGIDLSQVY(C) corresponding to peptides 429 to 449 of the abl oncogene (formerly 548 to 568 of the v-abl oncogene).
Spleen cells were fused with Sp2/0 myeloma cells.
In ELISA testing, the antibody reacts with the abl sequence. No binding activity was detected for the homologous region of FES, v-erb B, v-src, SRC, v-yes, RAF-1, v-raf, fms, v-fps, v-ros, HIR, v-mos, and SYN.
In immunoblot testing a protein of approximately 40 kd is detected in ANN-1 and src transformed cells.
The IgG1 reactivity of the antibody with the ABL peptide (429 to 449) was confirmed by ELISA. IgG1 was strongly positive while IgG2b was negative.
