10K+random+peptide+array

density of spot on array
 * Peptide Concentration: 1 mg/mL
 * 1 mg/mL*1g/1000mg*1mol/(110*20)g*1000mmol/1mol = 4.55*10^(-4) mmol/mL or 0.455 umol/mL
 * Corresponding density per surface area: 0.455 umol/mL*0.3mL/(Pi*(70um)^2) = 8.87 mol/m^2
 * Spot volume: 300 uL
 * Spot size is about 140 um in diameter
 * see 6-29-12 e-mail from Zbig for original source
 * average molecular weight of amino acid (110 Daltons) (http://www.genscript.com/conversion.html)
 * Phil said that on the aminosilane slides the peptides are about 1 nm apart so there would be about 4 peptides/(1 nm^2)
