It is investigated in cellular motility models for its capacity to sequester monomeric G-actin, regulate actin polymerization kinetics, and support cytoskeletal reorganization during cellular migration assays.

Reconstitution should be conducted under sterile conditions using bacteriostatic water (0.9% benzyl alcohol) or sterile laboratory saline. Allow the diluent to run gently down the interior vial wall; avoid vigorous shaking or vortexing to prevent shear-induced degradation. Reconstituted aliquots must be stored at 2°C to 8°C and evaluated within 28 to 30 days.\n  \u003c\/p\u003e\n\n  \u003cdiv style=\"background-color: #FAF2F2; border: 1px solid #EAC8C8; border-radius: 8px; padding: 16px 20px; margin-top: 24px; color: #5C1820; line-height: 1.6; font-size: 13.5px;\"\u003e\n    \u003cstrong style=\"color: #8C1D28; display: block; margin-bottom: 6px; font-size: 14px; letter-spacing: 0.02em;\"\u003eREGULATORY COMPLIANCE NOTICE\u003c\/strong\u003e\n    All èvelan research products are strictly synthesized and supplied for laboratory research, analytical characterization, and scientific assay evaluation only.
