Introduction
Congratulations on taking a big step towards improving the affordability, quality and speed of your genomics, biomedical, pharmaceutical and agricultural research. This booklet contains all the information required to take full advantage of Arrayit SuperStreptAvidin Microarray Substrates.

Quality Control
Arrayit takes every measure to assure the quality of our Arrayit Brand Super Microarray Substrates. The finest microarray biochip cleanroom research was used to develop these products. Rigorous quality control monitoring on a substrate-by-substrate basis guarantees that each these products conforms to the highest industry standards.

Product Description
This surface starts with ArrayIt SuperClean 2 glass then it is activated with superstreptavidin to bind biotinylated biomolecules. Streptavidin is protein isolated from streptomycetes avidinii that has an irreversible binding affinity for biotin. The superstreptavidin is covalently bound to the surface and will not flake, crack or peel off. The surface as a low intrinsic background and has a high binding capacity. SuperClean 2 is a highly polished glass surface with an optical smoothness tolerance of 50 angstroms over the entire 25mm x 76 mm surface area for optimum homogeneity; this new surface sets the highest quality standard for superstreptavidin-activated substrates for microarray applications. These substrates are packed in white slide boxes, vacuum packed and should be stored at 4°C.

Short Protocol Protein (Steps 1-7)
1. Suspend biotinylated protein samples in Protein Printing Buffer at 0.25-1 µg/µl.
2. Print protein samples onto SuperStrepavidin Substrates.
3. Block with SuperStreptavidin blocking buffer and then wash and dry the printed microarrays.
4. React the processed microarrays with fluorescent samples.
5. Wash the microarrays to remove un-reacted fluorescent material.
6. Scan the microarray to produce a fluorescent image.
7. Quantitate and model the fluorescent data.

Complete Protocol Protein (Steps 1-7)
1. Suspend biotinylated protein samples in 2X Protein Printing Buffer for a final protein concentration of 0.25-1 µg/µl. Perform transfers careful to prevent protein denaturation. Mix samples thoroughly prior to printing and transfer into 384-well microplates at 5-10 µl per well. Keep samples cold (4°C) at all times during sample preparation.
2. Print protein samples onto SuperStrepavidin Substrates. Use a Protein Edition Microarrayer such as the SpotBot® Pro or NanoPrint Protein Edition to print the biotinlylated protein samples on the SuperStreptavidin Substrates. Place the 384-well microplates onto the platen of the instrument and print the samples onto the glass SuperStreptavidin Substrate slides. For best results, make sure the microplates and glass slides remain at 4°C for the duration of the print run. Following the print run, incubate the printed substrate slides on the robot platen for 30 min at 4°C at ambient humidity, to allow binding of the biotyinlated proteins to the streptavidin molecules.
3. Block with SuperStreptavidin blocking buffer and then wash and dry the printed microarrays. Use a glass LifterSlip™ cover slip large enough to completely cover the printed microarray area. Place 100-200 µl of SuperStreptavidin Blocking Buffer onto the printed microarray and place a LifterSlip™ on top of the droplet of Blocking Buffer. Incubate for 60 min at 4°C or room temperature (20-25°C) to block the microarray surface. Following the blocking step, wash 3 times for 5 min each in 1X PBS and then for 10 sec in 0.1X PBS. Spin dry using a High Speed Microarray Centrifuge (Cat. MHC) and store the blocked microarrays in a slide box at 4°C.
4. React the processed microarrays with fluorescent samples. Use a LifterSlip™ and either hybridization cassettes or an automated hybridization station to react the processed microarrays with a fluorescent sample. Binding reactions are typically performed for 30-60 min at 4°C or room temperature (20-25°C), with fluorescent samples suspended in 1X SuperStreptavidin Blocking Buffer.
5. Wash the microarrays to remove un-reacted fluorescent material. Following the binding reaction, wash the microarrays 3 times for 5 min each in 1X PBS + 0.01% tween-20, and then for 10 sec in 0.1X PBS. Spin dry using a High Speed Microarray Centrifuge (Cat. MHC).
6. Scan the microarray to produce a fluorescent image. Use an Arrayit InnoScan® or SpotLight™ Microarray Scanner to obtain a 16-bit TIFF of the microarray.
7. Quantitate and model the fluorescent data. Use Arrayit Mapix software to quantify the TIFF data in preparation for data modeling.

Short Protocol DNA (Steps 1-7)
1. Suspend biotinylated DNA samples in Micro Spotting Solution Plus at 50 µM final concentration.
2. Print DNA samples onto SuperStrepavidin Substrates.
3. Block with SuperStreptavidin blocking buffer and then wash and dry the printed microarrays.
4. Hybridize the processed microarrays with fluorescent probe.
5. Wash the microarrays to remove unreacted fluorescent probe.
6. Scan the microarray to produce a fluorescent image.
7. Quantitate and model the fluorescent data.

Atomic-force-microscopy
Figure 2.
Atomic Force Microscopy (AFM) analysis. Shown are AFM scans of the SuperClean Microarray Substrate Slide by Arrayit, Sunnyvale CA. Data are coded to a rainbow intensity scale, such that red data represents 5.0 nm or 50 angstroms. The substrates have an average smoothness of 2.0 nm or 20 angstroms, which corresponds to about 10 silicon dioxide bonds.

microarray-slide-orientation
Figure 3.
Correct Substrate Slide Orientation. Shown is a graphic of two Arrayit Microarray Substrates, showing the correct and incorrect orientation for use. In the correct orientation (blue graphic), the chamfer will be located in the upper right corner and samples should be printed on the side facing upward, which is the same side that contains the word “Correct!”. In the incorrect orientation (red graphic), the chamfer will be located in the upper left corner, placing the backside facing upward, which is the side that contains the word “Incorrect!”. Only one side of Arrayit Microarray Substrates is suitable for printing. Please print on the correct side only.
