Solution Overview

Problem

Current methods fail to distinguish between leukemia cells resistant and susceptible to differentiation mediated by deltanoids, hindering effective therapy selection in acute myeloid leukemia treatment.

Innovation Solution

A method using antibodies, specifically scFv format antibodies obtained through phage display, to detect surface antigens on leukemia cells, differentiating between resistant and susceptible cells by employing SEQ ID NO: 1 for detection and SEQ ID NO: 2 as a negative control, preferably through flow cytometry or ELISA-type assays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional diagnostic methods are used, then general leukemia detection is possible, but differentiation between deltanoid-resistant and deltanoid-susceptible cells cannot be achieved

Engineering Contradiction:
Improveability to distinguish resistant vs susceptible cellsVSAvoidcomplexity of diagnostic method
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs flow cytometry with fluorescently labeled antibodies that bind to surface antigens on leukemia cells. The fluorescent signals produce distinct color/fluorescence patterns that allow visual and instrumental differentiation between deltanoid-resistant and deltanoid-susceptible cell populations, directly resolving the measurement precision limitation of conventional methods.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces specific antibodies as intermediary agents that recognize and bind to surface antigens uniquely expressed on deltanoid-resistant leukemia cells. These antibodies serve as mediators between the diagnostic system and the target cells, enabling specific identification and differentiation that conventional direct staining methods cannot achieve.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If rapid therapy selection is implemented, then treatment time is reduced, but accuracy in identifying susceptible cells may be compromised

Engineering Contradiction:
Improvetime for therapy selectionVSAvoidaccuracy of susceptibility determination
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The patent performs preliminary characterization of leukemia cells by detecting surface antigen expression patterns before initiating deltanoid therapy. By pre-identifying the presence or absence of specific surface antigens using flow cytometry, the system determines cell susceptibility in advance, enabling rapid and accurate therapy selection without compromising diagnostic accuracy despite the accelerated timeline.

Inventive Principle:
Principle #10Preliminary action
