Scientific capability / Plasma Competition and Covalent Capture

Can the target capture the molecule before something else does?

An extracellular covalent design faces competing reactions and loss processes. BioTwin models target capture alongside albumin competition, hydrolysis, reversal and clearance to identify which term may control the result.

Put target chemistry into its competing environment

An isolated target-reaction experiment is essential, but it leaves a separate question: what fraction of the opportunity survives the surrounding system? A competing-loss model tests how recognition, exposure and reaction assumptions affect target capture.

Find the parameter worth changing

If the model is limited by recognition, changing intrinsic reactivity may address the wrong problem. If exposure or a competing reaction dominates, a different experiment is needed. The output is a target-specific sensitivity analysis and a proposed design lever, conditional on the supplied rates and concentrations.

A worked computational investigation

In the Lp(a) program, BioTwin compared alternative molecular designs and their supporting assumptions, helping define a candidate program and a focused laboratory verification plan.

Recognition, chemistry and exposure belong in the same question

Candidate design and kinetic modeling can examine recognition, reaction conditions and exposure together. Combining results requires the same candidate and compatible assumptions; separate favorable calculations do not establish a favorable joint result.
