A capillary zone electrophoretic method for the study of formation of a covalent conjugate between microcystin LR and protein phosphatase 2A
Bibliographic record
Abstract
The study of conjugate formation between microcystin (MCYST)-LR and protein phosphatase (PP) 2A, which was isolated from bovine kidney and mouse brain, was achieved by using a highly efficient capillary zone electrophoretic (CZE) separation method. The MCYST-LR-PP2A conjugate (from bovine kidney) was resolved from its precursor after just 15 min of incubation. Moreover, the migration time, and, hence, the total analysis time, was less than 5 min. While the present findings of the time lag between conjugate formation and full inhibition are not novel, the CZE method does provide an alternative tool to HPLC with a higher separation efficiency to yield data for kinetic and mechanistic studies of the enzyme-toxin interaction. The CZE data reported here were found not to be adequately described by a first-order kinetic model. Moreover, the CZE method, which involves the use of a low ionic strength aqueous buffer, does not suffer from the drawback of the use of denaturing organic solvents such as those used in HPLC.

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.
