Cultrex Spheroid Formation Extracellular Matrix, 10X Summary

Provides specialized extracellular matrix optimized to drive aggregation and/or spheroid formation of cells as a part of the Cultrex 3-D Culture Spheroid Cell Invasion Assay.

Why Use Cultrex Spheroid Formation Extracellular Matrix, 10X?

The Cultrex 10X Spheroid Formation Extracellular Matrix (ECM) is a proprietary mixture of extracellular matrix proteins derived from murine EHS sarcoma and optimized for spheroid formation.  The diluted ECM is a fluid in culture that promotes cell-cell adhesion within a low adhesion environment.

Data Example

Embedding Spheroids in Cultrex BME for Cell Invasion and Migration Assays. MDA-MB-231 (3,000 cells/well) formed spheroids in low adhesion plates for 72 hours using reagents in the Cultrex 3-D Spheroid Basement Membrane Extract Cell Invasion Assay (Catalog # 3500-096-K). Briefly MDA-MB-231 cells were cultured in the presence of 1X Spheroid Formation Matrix (Catalog # 3500-096-01). Then spheroids were embedded in A) no Invasion Matrix, or B) Spheroid Invasion Matrix (Catalog # 3500-096-03). After hydrogel polymerization, DMEM and 10% FBS was added to each well to promote a chemotactic response over a 96 hour period. Note the addition of the Spheroid Invasion Matrix enhanced cell invasion over spheroids cultured without embedding in the invasion matrix.
