RNA Sample Requirements for ABI Arrays

This form must be filled out completely before we can accept any samples. Once this form has been filled out, please coordinate with James Sprague to drop off samples.

The most critical aspect of any microarray experiment is the quality of the RNA and failed microarray experiments due to problems with RNA quality is something that BIOGEM wishes to avoid. Therefore we require that the RNA is prepared with the RNeasy kit from Qiagen. This ensures high quality RNA which will not contain contaminants that interfere with enzymatic reactions.

In addition to the tubes of RNA supplied for labeling, please provide a separate aliquot for Agilent Bioanalyzer analysis. Provide the RNA for Agilent analysis at a concentration range of 0.3 mg to 1 mg per ml at a volume of no less than 3ul. Label these tubes with an “A” (denoting they are for Agilent analysis).

Label the labeling aliquot tubes with these information:

Your name.
Date of sample submission (day/month/year).
Name of platform requested ("ABI").

Summary of RNA Requirements:

Amount of RNA REQUIRED for Agilent Bioanalyzer analysis: 0.3mg to 1 mg/ml at a volume of no less than 3ul. Do NOT dilute the Bioanalyzer aliquot as concentration of the labeling aliquot will be based on this.
Amount of RNA REQUIRED for labeling : 1-5 ug total RNA. (2 ug are used per experiment. We keep the extra in case the labeling fails the first time. We return any RNA we do not use if that is what the investigator wishes).
RNA 260/280 between 1.8-2.0.
Gel validation (if RNA quantities permit).
Ratio of high/low molecular weight rRNA: ~2.
RNA must be resuspended with RNAse-free water (NOT DEPC WATER) at a concentration of 1 mg/ml, concs less than this will incur an extra charge if we have to concentrate the material. Please let us know in advance if the RNA is at a lower concentration.

RNA quality will be checked at the facility. If low quality is suspected or the RNA fails to meet our criteria, the experiment will be stopped. Please contact James Sprague if you have any questions or concerns about the integrity of your RNA samples.
