Instructions

• The ibidi product family is comprised of a variety of µ-Slides, µ-Dishes, and µ-Plates, which have all been designed for high-end microscopic analysis of fixed or living cells.
• The glass bottom versions are especially designed for TIRF, super resolution and single molecule applications.
• The µ-Slide 15 Well 3D Glass Bottom (formerly µ-Slide Angiogenesis Glass Bottom) is a cell culture product for tube formation, angiogenesis assays and direct cell culture. Cells can be grown on or in gel matrices, e.g. Matrigel or directly on the glass coverslip bottom.

Attention!
Be cautious when handling ibidi labware products with glass bottom! The glass coverslip or glass slide is very fragile and might break easily. Handle with care to avoid physical injury and damage to devices through leakage of the medium.

Surface
The μ-Slide 15Well 3D Glass Bottom is manufactured with an uncoated glass coverslip. Washing steps (e.g. with PBS) before cell seeding can remove glass dust which is advantageous
for direct cell growth on the surface.

Coating
In tube formation assays the μ-Slide 15 Well 3D Glass Bottom is coated with a 0.8 mm thick layer of gel matrix.

1. Prepare your gel matrix according to the manufacturer’s protocol or reference.
2. Fill the inner well with 10 μl liquid gel. Avoid air bubbles.
3. Let the gel polymerize under appropriate conditions.
4. Use as soon as possible.
5. If storage is needed fill sterile water around the wells to generate a humidified environment to hinder evaporation.

Non-gel based coatings are also possible. Please use 10 μl coating solution and calculate with an area to be coated of 0.23 cm2 per well. Further information about coatings is provided in Application Note 08 ”Cell culture coating”.

Tube Formation Assays

In a tube formation assay cells are seeded on top of the polymerized gel matrix:

1. Trypsinize and count cells as usual. Dilute the cell suspension to the desired concentration. Depending on your cell type, we recommend 1–3 ×105 cells/ml.
2. Apply 50 μl of the cell suspension into the upper well. Do not touch the gel matrix with the pipet tip.
3. Cover the μ-Slide 15 Well 3D Glass Bottom with the supplied lid. Incubate at 37°C and 5% CO2 as usual.
4. Conduct your experiment.
5. Depending on the cell type, medium exchange is necessary every 1–2 days. Carefully aspirate the old medium and replace it by 50 μl fresh medium.

• For a detailed protocol please refer to Application Note 19 ”Tube Formation” and Application Note 5 ”Tube Formation in μ-Plate 96Well 3D”.
• Further information about the optimization of experimental parameters and data analysis is provided in Application
  Note 27 ”Tube Formation – Data Analysis”.

Tip:

• Air bubbles in the gel can be reduced by equilibrating the μ-Slide 15Well 3D Glass Bottom before usage inside the incubator overnight.
• In case bent gel surfaces are created, increase or decrease the amount of gel used, until you get flat and even gels.

Tip:

• For less evaporation the space in-between the wells can be filled with sterile water or agarose. Add agarose to water or buffer solution (e.g. 0.1 g to 10 ml water). Melt agarose solution using a microwave or boiling water bath and allow the solution to cool to ∼50°C.

Seeding Cells in 2D

You can also use the μ-Slide 15Well 3D Glass Bottom for a standard 2D cell culture without gel matrix.

1. Trypsinize and count cells as usual. Dilute the cell suspension to the desired concentration. Depending on your cell type, application of a 1.8– 4.3 × 105 cells/ml suspension should result in a confluent layer within 2–3 days.
2. Apply 10 μl cell suspension into each well of the μ- Slide 15 Well 3D Glass Bottom. Avoid shaking as this will result in inhomogeneous distribution of the cells.
3. Cover the slide with the supplied lid. Incubate at 37°C and 5% CO2 as usual.
4. After cell attachment, add 50 μl cell-free medium to fill the upper well.

Attention!

• Avoid evaporation during seeding and cell culture in the incubator! We recommend placing the μ-Slide 15 Well 3D Glass Bottom in an extra humidity chamber (e.g. a Petri Dish with wetted paper).

Undemanding cells can be left in their seeding medium for up to three days and grow to confluence there. However, best results might be achieved when the medium is changed every 1–2 days. Carefully aspirate the old medium and replace it by 60 μl fresh medium per well.

Experimental Setups

Alternatively, the μ-Slide 15 Well 3D Glass Bottom can be used for the following assays:

• Fill the inner well with cells suspended inside a gel matrix. After gel polymerization, add 50 μl cell-free medium to fill the upper well.

• Sandwich Cell Culture: Fill the inner well with a gel matrix. Seed cells on top of the polymerized gel and imbed the cells with 50 μl gel in the upper well.

• Fill the inner well with a low volume of the gel matrix, e.g. 8 μl. Seed cells, spheroids or tissue pieces on top of the polymerized gel. If necessary gently shake the slide to make the cells slide into the center of the well.

• Fill the inner well with fibroblasts suspended inside a gel matrix. Seed cells on top of the polymerized gel. Overlay the cell layer with medium and incubate for invasion of the cells into the gel matrix.

Microscopy

To analyze your cells, no special preparations are necessary. Cells can be directly observed live or fixed, preferably on an inverted microscope. The bottom cannot be removed. For optimal results in fluorescence microscopy and storage of fixed and stained samples, ibidi provides mounting media (50001 and 50011) optimized for μ-Dishes, μ-Slides, and μ-Plates.

• Note:
  When gel matrices are used the optical quality and the use of high magnification objective lenses might be restricted.

• Tip:
  For phase contrast imaging after the experiment, the upper well can be overfilled with additional 25 μl. Closing the lid eliminates the meniscus of the upper well. This will create perfect phase contrast images. Please keep in mind that this overfilling technique might lead to well-to-well crosstalk. Therefore, we recommend this for final examination using phase contrast microscopy only.
