https://pages.htgaa.org/2026b/shakera-karolia/week-03-hw-cell-free/index.htmlHTBAA Week 3 — Designing a Cell-Free Reaction Composition Section 3 (A–C) report — for submission on the homework website (version 2, 13 October 2026) Targets: sfGFP · PETase (TfCut2) · Reteplase Objective: lowest specific cost — $ per gram (sfGFP) or $ per unit of activity (PETase, Reteplase) Reading notes. All costs use the coopetition price list. Items marked [VERIFY] are not yet confirmed and are listed in Section 11. The three designs are hypotheses with stated tests, not predicted winners. Companion files: the workbook HTBAA_HW3_CFPS_Costing.xlsx (every figure below is a live formula there) and the CFPS Design Toolkit web page (Section 8), which recomputes these designs and checks them against this report.Hugoen
