3-D Culture Matrix^™ Mouse Laminin I may be used as a gel on which to grow cells, or as a media additive alone or in concert with other basement membrane components, to study cellular growth and differentiation in three dimensions in vitro. To offer the most standardized Laminin I for use in 3-D cultures, a special process is employed to provide material at a standard concentration of 6 mg/ml (by absorbance and extinction coefficient).

Solution in Dulbecco′s Modified Eagle′s medium containing 10 μg/ml gentamycin sulfate and no phenol red.

Functional Assay:
3-D Culture: Laminin I promotes differentiation of a human epithelial cell line derived from mammary gland (MCF-10A) into acinar structures.
Cell Attachment: Tested for the ability to promote cell attachment and spreading of MG63 human osteosarcoma cells.

Sterility Testing:
No bacterial or fungal growth detected after incubation at 37°C for 14 days following USP XXIV Chapter 71 sterility test.No mycoplasma contamination detected by PCR.Endotoxin concentrations = 20 EU/ml by LAL assay.

Storage Conditions and Product Stability:
Product is stable for a minimum of 3 months from date of shipment when stored at -80 °C in a manual defrost freezer. For optimal stability, store at -80 °C in aliquots. Avoid repeated freeze/thaw cycles.
