Use scikit-image watershed for rule-based segmentation; use Cellpose when deep learning generalization across staining conditions is needed.

Adaptyv Bio provides an API and Python SDK for ordering and managing cell-free protein expression and binding assay experiments. Use it to submit protein sequences for expression (scale 10–100 µg), characterize binding affinity (KD) against target proteins, track experiment status, and retrieve results — all programmatically without wet-lab setup. Designed for protein engineers, ML-guided directed evolution, and antibody/nanobody optimization workflows. Requires an Adaptyv Bio account and API key.

Structured ideation methods for scientific research: SCAMPER, Six Thinking Hats, Morphological Analysis, TRIZ, Biomimicry, and 4 more techniques. Decision framework for choosing methods by challenge type (stuck, improving existing, systematic exploration, contradiction resolution). Use when generating research ideas, exploring interdisciplinary connections, or challenging assumptions.

Analyze competitor pricing strategies across e-commerce platforms. Map price positions, identify pricing gaps, evaluate price elasticity signals, and develop data-driven pricing strategies.
