Characterization of the monoclonal antibody (mAb) crystalline mAb‐laden alginate hydrogel particles. a) Relationship between the mAb concentration in the pre‐gel suspension and the particle loading. b) Soft deformable hydrogel particles allow high effective volume fractions even at high antibody loadings. c) Encapsulation efficiency defined as the amount of mAb encapsulated relative to the total amount of mAb crystals in the pre‐gel suspension. Hydrogel particles were formed using 1% w/v mannuronic rich alginate (VLVM). The experiments were carried out from low (50 mg mL⁻¹) to high (400 mg mL⁻¹) mAb concentration in the pre‐gel.
