<h4>Sample Requirements</h4>
<strong>Intact Mass Analysis</strong>
<em>Concentration</em>: Optimally, 10uM. Samples at 1uM work if they are clean and very low buffer and salt content. 
 
<em>Buffer</em>:  Samples presented in water or other volatile solvents are best.  If your sample is not compatible with those requirements, then use a low salt buffer (< 50mM).  Try to avoid phosphate buffers as they quench the signal on the MALDI.  Avoid DMSO or glycerol if possible.  If not, keep percentage of glycerol/DMSO to <5%.
 
<em>Volume</em>: 1-10ul.  More is better.
 
<em>Containers</em>: Eppendorf type tubes, with your initials, sample name and date clearly on tube.

<strong>Samples for digest and protein identification:</strong>
<em>Amount</em>: Optimally, >500 fmol or >50 ng.  We can detect as low as 5 ng of protein but the coverage is not great, and the identification is less likely to work.  For post-translation modification searches, it is important to give at least 4-5 pmol of sample.
 
<em>Stain</em>: Coomasie, Sypro,  or other mass spec compatible silver stain.  Stay away from silver stain containing gluteraldehydes.  Do not over-stain gel.
 
<em>Controls</em>: Please provide blank portion of gel.  For your benefit provide a known, not pre-stained, standard.  Controls are not charged.
 
<em>Containers</em>: Place gel slice in methanol rinsed 1.5ml Eppendorf tube.(No need for additional liquid).  Clearly label all tubes with your initials, sample name and date.
