Establishment of Hybridoma Cell Lines Producing Monoclonal Antibodies Against Hepatitis B Virus Surface Antigens (a, d, and r) and Development of Sensitive ELISA Diagnostic Test
Bibliographic record
Abstract
A new treble-coated enzyme-linked immunoadsorbent assay (ELISA) kit of detecting Hepatitis B virus (HBV) surface antigen subtypes a, d and r (HBsAg-a, -d, -r) was developed by using four established hybridoma cell lines, of which two specifically secrete monoclonal antibodies (MAbs) against HBsAg-a (anti-HBsAg-a), one against -d (anti-HBsAg-d), and one against -r (anti-HBsAg-r). The approach of hybridoma cell lines' establishment were by fusing myeloma cells (SP2/0) with splenocytes from BALB/c mice immunized with a mixture of HBsAg-a, -d, -r. The ascitic MAb productivity of the four cell lines was at the titres of 1:10(6)-1:10(8). A treble-coated ELISA based HBV diagnostic kit was developed for detecting all of the three responding subtypes of HBsAgs. A 96-well ELISA microplate was coated with anti-HBSAg-a, -d, -r at a ratio of 3: 1: 0.5, with a horseradish peroxidase (HRP) conjugated anti-HBsAg-a as the labelled antibody. For clinical application, the new developed diagnostic kit detected HBsAgs of adr, adw, ayr, and ayw at a rate of lower than 0.25, 0.25, 0.5, and 0.5 ng/mL, respectively. Results indicated that this kit was more rapid and sensitive than that other current ELISA-based kits coated with a single MAb (e.g., anti-HBsAg-a).

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.
