        FAQs


        Are the inserts in our vector in a pri-miRNA format or a mature miRNA format?
        Majority of our inserts are in the pri-miRNA format (about 500-600bp in size). If the miRNA is found in a cluster, the insert will then be the mature miRNA format (about 150bp in size) to ensure that the construct is only expressing one miRNA. If the R in mir is big (miR) and the accession# is MIMA#########, then it’s typically the Mature format. If the r in mir is small (mir) and the accession# is MI#########, then it’s typically the pre-miRNA format. This information can also be found on the "insert type" section of this product webpage.
        It is mentioned that the regular (untouched) 293T cells are to be maintained in 500ug/ml of geneticin (G418). Is this correct? If yes, please explain.
        Yes, 293T cells are resistance to Geneticin(G418), as the drug was originally used to select cells expressing the SV40 large T antigen. Just like any other stable cell line generated, the cells should be kept at lower concentration of the selection drug to keep the selection pressure. Please note, that in this case since these wildtype cells are stably transfected with puromycin resistance gene, just adding puromycin may be sufficient to keep the selection pressure for the gene of interest.
        What is the molecular weight and how many ug of MCH00000 is in 2.5nmol?
        Cat. No. MCH00000 miRNA Mimic Negative Control is 6279 g/mole. For each vial (1.25nmol), it is 17.185µg, thus the total 2.5nmol equals to 34.37µg.
