Solution Overview

Problem

Existing assays fail to correlate changes in cellular functionality induced by perturbation elements back to specific examination areas, limiting the understanding of dynamic cellular responses and combining them with static functionality changes.

Innovation Solution

Uniquely labeled perturbation beads with optically detectable labels and perturbation oligonucleotides that code for both the perturbation element and unique labels, allowing correlation to specific examination areas through capture beads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If capture beads are pooled for sequencing, then static functionality information is obtained, but information correlating changes back to specific examination areas is lost

Engineering Contradiction:

Improveinformation correlationVSAvoidassay processing

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

A unique identifier oligonucleotide is introduced as an intermediary component on the perturbation bead that gets released and captured along with cellular nucleic acids. This intermediary carries the correlation information from the specific examination area through the pooling process, enabling traceability of static functionality changes back to their origin without requiring separate processing of each examination area.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent combines the unique identifier oligonucleotide with the perturbation element on the same bead, and subsequently merges these identifiers with cellular nucleic acids during the capture and pooling process. This merging allows all correlation information to be consolidated in a single pooled sample that can be sequenced while retaining the ability to trace changes to specific examination areas.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If only static functionality changes are measured, then endpoint analysis is simplified, but dynamic cellular responses during the assay are missed

Engineering Contradiction:

Improveassay throughputVSAvoiddynamic response information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The unique identifier oligonucleotide is pre-loaded on the perturbation bead before the assay begins. This preliminary action ensures that the correlation information is already in place to track both dynamic changes during the assay and static changes at the endpoint, without requiring additional steps during or after the assay execution.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If perturbation beads are uniquely labeled with optically detectable labels, then correlation to specific examination areas is enabled, but bead complexity increases

Engineering Contradiction:

Improvebead identification accuracyVSAvoidbead structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The unique identifier oligonucleotide serves multiple functions: it acts as a unique barcode for identification, serves as a capture target for the capture bead, and enables correlation between the perturbation element and the examination area. This multi-functionality reduces the need for separate components for each function, thereby reducing overall complexity despite the added identification capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of using complex optical labels or physical markers on the bead surface, the patent uses a molecular copy - the unique identifier oligonucleotide sequence - that encodes the identification information. This molecular copying approach is simpler to implement and manipulate than physical optical labels while providing equivalent identification precision.

Inventive Principle:

Principle #26Copying

AI summary

Disclosed are uniquely labeled perturbation beads used alone or in combination with a capture bead. These perturbation beads are useful in drug discovery especially in assays conducted in a mapped assay device. Such a uniquely labeled perturbation bead, when used in an examination area of a mapped assay device, allows for correlating the sequence of nucleic acids and other components from a lysed cell to the specific examination area where the nucleic acid was retrieved.
