SEQUENCING

WHAT THE FACILITY WILL DO: The facility will sequence single-stranded and double-stranded DNA samples (plasmid or PCR products) using ABI 377 or 373 automated DNA sequencers. We expect to provide 400-700 b of sequence per sample (depending on DNA quality and sequence). Results are available within 2 working days. The letter code sequences will be emailed to the requesting researchers; sequencer traces will be sent by inter-Lab mail.

COST: $20 per sample. If our first attempt to obtain a sequence is unsuccessful, a second reaction and run will be performed at no additional charge. If both attempts are unsuccessful, the charge will still be $20/sample.

HOW TO SUBMIT SAMPLES: Please use the request form and send your request by email to Ying Zou at yzou@lbl.gov). Please do not submit request forms by fax or mail.

Bring your clearly marked samples, together with a hard copy of the request form, to Building 84, Room 355. You need not call ahead - there is a clearly marked shelf in a designated freezer in 84-355, and you can simply leave your samples there.

WHAT TO SUBMIT: The request form describes the DNA and primer concentrations and sample volumes that we require (sufficient for two reactions). The facility will provide T3, T7, Universal and Reverse primers. All other primers must be provided by the requesting investigator.

Please provide the samples and primers in the exact concentrations and volumes specified on the request form. We strongly recommend that your DNA samples be purified by Qiagen or Promega kits or similar means. If you use a simple mini-prep procedure, please provide a picture of a gel on which the sample is run along side a standard. This will help us trouble-shoot if the first sequencing reaction fails.

QUESTIONS: Please call (x2217) or email (yzou@lbl.gov) Ying Zou if you have any questions.


cDNA EXPRESSION ARRAY SERVICES

We are pleased to announce that the LSD Cell Genotyping and Phenotyping (CG/P) core facility is now accepting RNA samples for microarray hybridization and analysis by special software on a charge-back basis.

WHAT THE FACILITY WILL DO:
OPTION ONE: The facility will take total RNA samples or poly A + RNA samples, hybridize them to Clontech Atlas human or mouse cDNA expression arrays (each with 1,176 or 588 genes), generate phosphor images of the hybridized membranes, and analyze them using AtlasImage software. The data will be presented as a report in the form of an Excel Spreadsheet. This report will show the relative signal itensities and include the comparisons of the signal intensities of two samples. It will be stored on a CD for you and sent via email as well.

OPTION TWO: The facility will take hybridized membranes and generate the phosphor images using our Cyclone phosphorimager or just the phosphor images and analyze them with our software. Simply supply a pair of matched phosphorimages or scanned autoradiographs in TIFF format. The data will be stored on a CD for you and sent via email as well.

COST: $1,800 per HYBRIDIZATION experiment (analysis of two samples), which start with RNA samples to report and CD deliver to you. $199.00 per comparison of two images that you create in TIFF format.

HOW TO SUBMIT SAMPLES: Please use the microarray service request form and send your request by email to Ying Zou at YZOU@LBL.GOV. Bring your *clearly marked* samples on dry ice together with a hard copy of the request form, to Building 84, Room 355. You need not call ahead - there is a clearly marked shelf in a designated -80C freezer in 84-355, and you can simply leave your samples there.

WHAT TO SUBMIT: The enclosed form describes the RNA concentrations and sample volumes that we require (sufficient for two reactions) include a photograph (total RNA) of your samples, along with OD readings.

QUESTIONS: Please email Ying Zou at YZOU@LBL.GOV or call (X2217) if you have any questions.

MORE CG/P INFO: The CG/P facility was established by an LDRD grant last year. Our long term aim is to provide sequencing (including SAGE) and microarray analyses to LSD investigators. Ying is the manager of the CG/P facility, and she is working with Goberdhan Dimri, the facility's molecular biologist, to develop and optimize the microarray and SAGE analyses. The facility is co-directed by Judy Campisi, Paul Kaufman and Kunxin Luo.
