microRNA Isolation Kit, Human Ago2 can prepare high purified fractions of microRNA, which binds with

human Argonaute2 (hAgo2) protein, based on immunoprecipitation method by using a high affinity

monoclonal antibody against hAgo2.

The name microRNA (miRNA) is given to functional, low molecular weight RNA comprising approximately 22

ribonucleotides. Such microRNA is known to regulate gene expression and play a role in the transcriptional

mechanisms of eukaryotic cells. Mature microRNA in the cytoplasm and nucleus will be introduced through

several processing pathways to RNA -induced silencing complex (RISC) and transferred to target mRNAs to

suppress the translation. Argonaute 2 (Ago2) is one of the main components of RISC.

This microRNA isolation kit can be used to prepared high purity fractions of microRNA based on

immunoprecipitation methods using a high affinity anti-Human/Mouse Ago2 monoclonal antibody. The

purified microRNA fraction contains very little contamination from rRNA and tRNA degradation fragments.

This kit will highly improve the microRNA cloning effi ciency compared with conventional microRNA

purification method.

Figure. 1 Purification of microRNA fraction

 by using microRNA Isolation Kit, Human

 Ago2 (Wako catalog #292-66701).

 The purified microRNA fraction from human

 cultured cell lines (HeLa, HepG2, HEK293)were

 specifi cally detected by Urea-PAGE. Cell

 number of each cell line is approximately 5 ¡¿106.

 The applied volume per lane is half of 10¥ìL of

 final solution prepared with an IP by this kit.

 

 

Cloning of purified microRNA from HeLa cells

High efficiency of microRNA cloning by using this kit followed by using microRNA Cloning Kit wako.

 

Procedure of microRNA cloning

1) The microRNA fraction was prepared by microRNA Isolation Kit, Human Ago2 (#292-66701) from

    5 x 106 HeLa cells.

2) The cDNA encoding microRNA was synthesized by microRNA Cloning Kit wako(#290-66501)

    and was inserted into T-vector.

3) The 96 transformants of E.coli were randomly selected from LB agar medium containing antibiotics.

4) Inserted cDNA sequences were determined by DNA sequencer and were collected sequences by using

   Sanger miRBase.

The presence ratio of microRNA was more than 90%.

Others indicated that isolated cDNAsequences were

not matched in a miRBase. Unknowns indicated that

isolated cDNA sequenceswere not matched human

genome sequence.The contents of cloned microRNA

species were indicated on Table 1.
