Arrayit offers innovative hardware solutions for creating multi-well microarrays on a single glass substrate slide. Reaction cassettes containing 8, 16, 24, 48 or 96 wells utilize silicone gaskets to create individual reaction wells encompassing the printed microarrays. The upper portion of the Hybridization Cassette allows the introduction of individual samples, making these cassettes ideal for DNA and protein microarray research and diagnostics.

Figure 2. Diagramatic depiction of the wells formed by Hybridization Cassette 1x24 (left) and 1x16 (right). Use these spacing coordinates to program the microarrayer prior to printing the 3x8 (1x24) or 2x8 (1x16) microarray patterns required to utilize the multi-well Hybridization Cassettes. Use the SpotBot and NanoPrint Microarrayer to simplify the microarray manufacturing using these formats. NOTE! It is possible to cut the ribs in these gaskets to make larger size reaction areas!

Figure 3. Hybridization Cassette 4x16 (Catalog ID AHC4X16) is identical to Hybridization Cassette 1x16 except that it contains four identical units allowing the use of four glass substrate slide microarrays. The Hybridization Cassette 4x16 has a 7.5 x 7.5 mm well size set at 9 mm centers in four identical 2x8 units. Well openings in the top portion of the Hybridization Cassette (shown here) are 5.5 x 5.5 mm. Requires the use of four individual silicon gaskets (Catalog ID GAHC1x16) to demarcate the individual wells, and the four gaskets are included with the purchase of the AHC4x16 product. Easily sealed with foil seals to prevent evaporation.

Figure 4. Hybridization Cassette 4x24 (Cat. AHC4X24) is identical to AHC1x24 except that it contains four identical units, allowing the use of four glass substrate slides. AHC4x24 has a 7.5 x 6.5 mm well size set at 9 mm centers in four identical 3x8 units. Well openings in the top portion of the cassette are 5.5 x 5.5 mm. The AHC4x24 equires the use of a silicone gasket (Cat. GAHC4x24) to demarcate the individual wells. The GAHC4x24 is included with the purchase of the AHC4x24 product. The top of the cassette is easily sealed with foil seals to prevent evaporation.

Figure 5. Silicone Replacement Gaskets for multi-well microarray Hybridization Cassettes. Use Replacement Gasket GAHC1x16 (upper left) with Hybridization Cassette AHC1x16, Replacement Gasket GAHC1x24 (upper right) with Hybridization Cassette AHC1x24, Replacement Gasket GAHC1x16 four each (lower left) with Hybridization Cassette AHC4x16, and one Replacement Gasket GAHC4x24 (lower right) with Hybridization Cassette AHC4x24. To prevent leakage during use, gaskets must be used in the proper orientation with the wide portion placed against the hybridization cassette top and the thin portion placed against the glass substrate slide. NOTE! It is possible to cut the ribs in these gaskets to make larger size reaction areas!

Figure 6. Schematic drawing for Arrayit Hybridization Cassette 4X8S (Cat. AHC4X8S). AHC4X8S holds 4 glass substrate slides 1 x 25 x 76 mm and gaskets define 8 x 4 wells, with the 8 wells down the slide spaced at 9 mm centers. For larger wells, use Cat. ACH4X8L (see Fig. 7).
