Description

Globin mRNA Depletion Probe (Human) is designed to remove human Globin mRNA. It can effectively remove Globin mRNA from adult, infant and embryonic sources, including HBA1/2, HBB, HBD, HBM, HBG1/2, HBE1, HBQ1 and HBZ. This product is used with Hieff NGSTM MaxUp rRNA Depletion Kit (Human/Mouse/Rat) (Yeasen#12253) to effectively remove rRNA and Globin mRNA from total RNA. This kit is suitable for both intact and degraded RNA samples. The RNA samples after rRNA & Globin mRNA removal can be used for high-throughput sequencing analysis of mRNA and non-coding RNA, which significantly enhance the proportion of valid data in sequencing results, and cDNA synthesis or other downstream applications.

Application:
Suitable for 100 ng~1 μg total RNA samples human, mouse and rat blood resource, and for both intact or partially degraded RNA samples.

Instructions
1. Probe Hybridization to RNA
1.1 Dilute 10 ng–1 μg of total RNA with Nuclease-free Water to a final volume of 10 μL in a PCR tube. Keep the RNA on ice.
1.2 Assemble the following RNA/Probe hybridization reaction on ice according to Table 1.
Table 1 RNA/Probe hybridization reactionrn

1.3 Mix thoroughly by gently pipetting up and down at least 10 times. Briefly spin down the tube in a microcentrifuge to collect the liquid from the side of the tube.
1.4 Place tube in a thermocycler and run the following program in Table 2 with the heated lid set to 105°C.

2.2 Mix thoroughly by gently pipetting up and down at least 10 times. Briefly spin down the tube in a microcentrifuge to collect the liquid from the side of the tube.
2.3 Place tube in a thermocycler and run the following program: lid 50°C; 37°C, 30 min; 4°C, hold.
3. DNase I Digestion
3.1 Assemble the following DNase I digestion reaction on ice according to Table 4.
Table 4 DNase Ⅰ digestion reactionrn

Components	Volume (μL)
DNase I Buffer	27.5
DNase I	2.5
RNase H treated RNA (Step 2.3)	20
Total	50

3.2 Mix thoroughly by gently pipetting up and down at least 10 times. Briefly spin down the tube in a microcentrifuge to collect the liquid from the side of the tube.

3.3 Place tube in a thermocycler and run the following program: lid off; 37°C, 30 min; 4°C, hold.

4. RNA Purification

4.1 Equilibrate the Hieff NGSTMRNA Cleaner (Cat#12602) to room temperature and resuspend the beads thoroughly by vortexing before use.

4.2 Add 110 µL (2.2×) beads to the RNA solution from Step 3.3 and mix thoroughly by pipetting up and down at least 10 times.

4.3 Incubate at room temperature for 5 minutes to bind RNA to the beads.

4.4 Place the tube on a magnetic stand to separate the beads from the supernatant. When the solution is clear (about 3 mins), discard the supernatant. Be careful not to touch the beads with the pipette tips.

4.5 Keep the tube on the magnetic stand. Add 200 µL of freshly prepared 80% ethanol to the tube. Incubate at room temperature for 30 seconds and then discard the supernatant. Be careful not to touch the beads with the pipette tips.

4.6 Repeat Step 4.5 once for a total of two washes.

4.7 Remove residual ethanol with 10 µL - pipette tips. Keep the tube on the magnetic stand and air dry-the beads for up to 5 minutes with the lid open.

4.8 Remove the tube from the magnetic stand. Elute the RNA from the beads by adding 11 μL of Nuclease-free Water. Mix thoroughly by pipetting up and down at least 10 times and briefly spin the tube.

4.9 Incubate for 5 minutes at room temperature. Place the tube on the magnetic stand until the solution is clear (~ 3 minutes).

4.10 Transfer 10 µL of the supernatant to a nuclease-free tube.

Note: If you need to stop at this point, samples can be stored at –80°C.

Usage Notes	1. Please use consumables that are free of RNase contamination and clean the experimental area regularly. It is recommended to use ThermoFisher's RNAZapTM high-efficiency nucleic acid removal spray to remove RNase contamination. 2. The RNA sample should be free from genomic DNA contamination. If gDNA remains in the sample, it should be digested by DNase I and purified before use. 3. The maximum input volume of RNA sample is 10 μL. If the sample volume is large, it can be concentrated first. 4. For your safety and health, please wear lab coats and disposable gloves for operation. 5. For research use only!

Storage	All the components are shipped with dry ice and can be stored at -20°C for one year.
