`RE: Fwd: 454 sequencing
`
`Hi christina,
`
`The reagent lead time tends to be about 3 weeks or so from Illumina. we
`don't currently stock kits in the CAT.
`I e-mailed Steve and told him the
`fastest way would probably be to ask Joe DeRisi if his lab has available
`reagents.
`I know he and Jonathan Weissman bought several kits a while back
`and I don't believe they have used them all yet. Perhaps ask Steve if he
`has contacted Joe yet, and if not go ahead and fire off an e-mail to Joe and
`ask.
`
`Best,
`clement

`
`Hi clement,
`I am a student in Steve's lab and I am the person working on the solexa
`sequencing project.
`I have already prepared a library. I would like to know how soon you
`would be able to receive the sequencing reagents for 36nt readlength. I
`heard that the reagents are back-ordered and wonder if your lab can
`somehow get them faster?
`Thanks for your help!

`thanks for dropping by the other day - it was a big help.
