Agilent Small RNA Kit

Quick Start Guide

The complete Small RNA Kit Guide can be found in the online help of the 2100 Expert software.

Assay Principles

Agilent RNA kits contain chips and reagents designed for analysis of RNA fragments. Each RNA chip

contains an interconnected set of microchannels that is used for separation of nucleic acid fragments based

on their size as they are driven through it electrophoretically. Agilent RNA kits are designed for use with the

Agilent 2100 Bioanalyzer instrument only.

Applications and Kits

Agilent Small RNA kits are designed for the analysis of total RNA (eukaryotic and prokaryotic) and samples

enriched for small nucleic acids.

Agilent RNA kits: RNA 6000 Nano Kit (reorder-no 5067-1511), RNA 6000 Pico Kit (reorder-no 5067-1513),

and Small RNA Kit (reorder-no 5067-1548).

Storage Conditions

•Freeze unopened Small RNA ladder at -20 °C. Prepared ladder aliquots need to be stored at -70 °C. Keep

all other reagents and reagent mixes refrigerated at 4 °C when not in use to avoid poor results caused by

reagent decomposition.

•Protect marker solution (contains a fluorescent dye), dye and dye mixtures from light. Remove light

covers only when pipetting. Dye decomposes when exposed to light.

Sample Preparation

•Prepare RNA samples in deionized water. For analysis, total RNA should be between 1 – 100ng/μL,

purified small RNA samples (< 150nt) should be 1 – 20ng/μL, and oligonucleotides should be 100 –

2000pg/μL. If concentration of a sample is above these ranges, dilute with RNase-free water.

Specifications

Setting up the Chip Priming Station

Replace the syringe:

Unscrew the old syringe from the lid of the chip priming station.

Release the old syringe from the clip. Discard the old syringe.

Remove the plastic cap of the new syringe and insert it into the clip.

Slide it into the hole of the luer lock adapter and screw it tightly to the chip priming

station.

Adjust the base plate:

Open the chip priming station by pulling the latch.

Using a screwdriver, open the screw at the underside of the base plate.

Lift the base plate and insert it again in position C. Retighten the screw.

Essential Measurement Practices

•Handle and store all reagents according to the instructions on the label of the

individual box.

•Avoid sources of dust or other contaminants. Foreign matter in reagents and samples

or in the wells of the chip will interfere with assay results.

•Allow all reagents to equilibrate to room temperature for 30 min before use. Thaw the

sample on ice.

•Protect marker solution, dye and dye mixtures from light. Remove light covers

only when pipetting. The dye decomposes when exposed to light and this

reduces the signal intensity.

•Always insert the pipette tip to the bottom of the well when dispensing the

liquid. Placing the pipette at the edge of the well may lead to poor results.

•Always wear gloves when handling RNA and use RNase-free tips, microfuge

tubes and water.

•The gel matrix is very viscous! Proper pipetting and mixing requires special attention.

•It is recommended to heat denature all RNA samples and RNA ladder before use for 2 min at 70 °C (once)

and keep them on ice.

•Do not touch the Agilent 2100 Bioanalyzer instrument during analysis and never place it on a vibrating

surface.

•Always vortex the dye concentrate for 10 s before preparing the gel-dye mix and spin down afterwards.

•Use a new syringe and electrode cleaners with each new kit.

•Use loaded chips within 5 min after preparation. Reagents might evaporate, leading to poor results.

•To prevent contamination (e.g RNase), it is strongly recommended to use a dedicated electrode cartridge

for RNA assays.

•For cleaning of the electrode pinset inbetween runs, use RNase-free water only. Do not use RNaseZAP

unless for decontamination of the electrode pins. After using RNaseZAP, wash the pins thoroughly with

RNase-free water. Refer to the Kit Guide for details on electrode cleaning and decontamination.

Agilent Small RNA Assay Protocol

Preparing the RNA Ladder

Spin the ladder down.

Heat denature the ladder for 2 min at 70 °C.

Immediately cool the vial on ice.

Prepare aliquots in recommended 0.5 mL RNase-free vials with the required amount for typical daily use.

Store aliquots at -70 °C. After initial heat denaturation, the frozen aliquots should not require repeated

heat denaturation.

Before use, thaw ladder aliquots on ice (avoid extensive warming).

Preparing the Gel

Pipette the complete volume (approx. 650 μL) of the gel matrix (red ) into a spin filter.

Centrifuge at 10000g ± 20 % for 15 min at room temperature. Use filtered gel within 4 weeks. Store at

4°C.

WARNING

Handling DMSO

Kit components contain DMSO. Because the dye binds to nucleic acids, it should be treated as a

potential mutagen and used with appropriate care.

➔

Wear hand and eye protection and follow good laboratory practices when preparing and handling

reagents and samples.

➔

Handle solutions with particular caution as DMSO is known to facilitate the entry of organic

molecules into tissues.
