Abstract
RP215 monoclonal antibody (Mab) was initially generated against OC-3-VGH ovarian cancer cells and was shown to react with a cancer-associated carbohydrate epitope in glycoproteins designated as CA215. Additional five high affinity Mabs, designated as RCA-10, -100, -104, -110 and -111, respectively, were generated by using affinity-purified CA215 as the immunogen in this study. All RCA Mabs were found to recognize periodate-sensitive carbohydrate-associated epitope(s) and to pair with RP215 in typical sandwich enzyme immunoassays for the quantification of CA215. When compared with those of RP215, the amino acid sequence homology of the Fab regions ranged from 100% for RCA-100 to 65% for RCA-110, based on which 3 distinct Mab groups were categorized. In vitro TUNEL apoptosis and complement-dependent cytotoxicity assays were performed with these Mabs and found to have comparable inhibitory efficacy to cancer cells. Results of biochemical and immunological assays revealed that RP215, RCA-100 and RCA-10 react with the linear carbohydrate-associated epitope, whereas the others recognize the conformational form of the epitope in CA215. This study has suggested that the unique carbohydrate-associated epitope(s) is immunodominant in mice when immunized with CA215. It remains to be demonstrated if the differential anti-cancer efficacy exists among the distinct groups of these anti-CA215 Mabs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
