Product Description

ECM Select® Array Kit Ultra-36 is an extracellular matrix screening array. This product has thirty six (36) human extracellular matrix protein (ECM) conditions that are deposited onto the hydrogel surface as printed array spots.  Each ECM condition is printed with nine (9) replicate spots where each spot has diameter of 200-400 µm.  The ECMs are localized within each spot without cross diffusion from neighboring spots, therefore each spot represents an independent ‘well’ or experiment.

The ECM Select® Array Kit Ultra-36 contains a microscope glass slide printed with the ECM conditions contained within a protective slide holder and a pre-sterilized tray.  The components are sterilized and ready-to-use.

Cells of interest are seeded on to the ECM Select® Array slide and allowed to be cultured in the incubator for the desired amount of time. Cell morphology, attachment and growth can be visualized using a bright field microscope. Specific cellular behaviors can be monitored by staining the cells on the slide using specific fluorescence based marker. Fluorescence signal can be detected using fluorescence microscope imaging system.

The ECM Select® Array Kit Ultra-36 is simple to use in comparison to performing the same experiment in multi-well tissue culture plates.  Cell seeding, fixing, washing and process steps are done in one single solution exchange, eliminating multi-well solution handlings. From start to finish, the optimal ECM for culturing cells can be determined in less than 24 hours for most cell types.

Product Q & A

Because it is contact printing, it is hard to determine the the precise amount. Based on protein staining result, each spot is about 0.1-1ng.

There may be possibility of antagonist effect of two different component. We have not seen this very often, what we usually see is one of the component by itself does not provide adhesion effect, but when combine with another ECM, greatly enhance the other ECM.

The stiffness is ~10 kPa.

Mounting media tends to destroy the polyacrylamide hydrogel that the ECM spots are printed onto.

There are two options:

Option 1: Incubate the entire slide  for 20 minutes with 4% PFA prior to the stain protocol. The slide was cover-slipped with a 90% glycerol medium containing the PPD anti-fade compound and sealed with fingernail polish around the edges.

Option 2: Fluoromount Aqueous Mounting Media (Sigma F4680-25ML) has worked for some customers in their labs but we have not tested this in-house.

Advanced BioMatrix manufacturers a majority of the proteins on the slide. Here is the full list of sources:

Collagen 1 Advanced BioMatrix #5007
Collagen III Advanced BioMatrix #5019
Collagen IV Advanced BioMatrix #5016
Collagen V Advanced BioMatrix #5168
Collagen VI Corning #354261
Fibronectin Advanced BioMatrix #5050
Vitronectin Advanced BioMatrix #5051
Tropoelastin Advanced BioMatrix #5052
Laminin Sigma #L6274

After drying, the slide is stable for a long time. However the fluorescence signal may not last very long. In order to avoid photo bleaching, store the slide in the dark.
