Isolation of a Purified Allergen from Kentucky Blue Grass Pollen
Bibliographic record
Abstract
An allergenic fraction, designated as C-I-2-6, was isolated from among the allergenic constituents present in the dialysate of the aqueous extract of defatted Kentucky blue grass (KBG) pollen by a combination of gel filtration, ion-exchange chromatography and preparative isoelectrofocusing. This fraction was shown in consist of glycoprotein with a molecular size corresponding to 10,000 daltons and of two compounds with closely related pI values (4.5--4.9); its protein moiety contained all the amino acids except cysteine. As demonstrated by crossed immunoelectrophoresis with a sheep anti-R serum, fraction C-I-2-6 shared the antigenic determinants of 2 of the 15 antigenic components of the nondialysable components, i.e. retentate (R) of the aqueous extract of KBG pollen. Remarkably, in spite of the markedly lower molecular weight than R, fraction C-I-2-6 possessed all the allergenic determinants of R responsible for inducing murine IgE antibodies.

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.
