Characterization of a Monoclonal Antibody Against CREPT, a Novel Protein Highly Expressed in Tumors
Bibliographic record
Abstract
CREPT (cell-cycle related and expression-elevated protein in tumor), a novel gene also called RPRD1B and C20ORF77, was recently identified to promote tumorigenesis through up-regulation of the expression of genes related to cell cycle. The previous study demonstrated that CREPT is highly expressed in a variety of tumors and enhances the expression of Cyclin D1 by promoting the formation of a chromatin loop. To study the correlation of CREPT expression with clinical factors in different tumors, we generated a monoclonal antibody (3E10) using purified recombinant human GST-CREPT protein as an antigen. In this study, we characterized the specificity of the monoclonal antibody and cloned the gene encoding the antibody for preparation of industrial production. Our results showed that the monoclonal antibody 3E10 was sensitive and specific to recognize human endogenous CREPT protein. We have mapped the epitope of the antibody and cloned the variable region sequence of the gene encoding the antibody. We confirmed that the cloned gene produced an equivalent antibody as that produced by the original hybridoma. This study provided a basis for large-scale production of the CREPT antibody, which will be useful for the study of the role of CREPT in different tumors.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
