density of spot on array

* Peptide Concentration: 1 mg/mL
  o 1 mg/mL*1g/1000mg*1mol/(110*20)g*1000mmol/1mol = 4.55*10^(-4)
    mmol/mL or 0.455 umol/mL
  o 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)

versions of cim10k arrays
10kv1
GSC on C terminal (right side of rest of sequence since sequences are listed N to C)

10kv2
GSC on N terminal (left side of rest of sequence since sequences are listed N to C)

10kv3
used D amino acids (written as lower case letters by our lab)
