摘要: The present invention provides methods and kits for determining which microRNAs bind to a target mRNA where the methods comprise the steps of (a) creating a bait sequence from the target mRNA, where the bait sequence comprises a label that binds to a binding agent; (b) adding a mixture of microRNAs to the bait sequence; (c) separating the microRNAs that bind to the bait sequence from those microRNAs that do not bind; and (d) identifying the microRNAs that bind to the bait sequence, wherein the microRNAs identified are those that bind to the target mRNA.

摘要: Methods and kits are provided for testing the functional effect of methylating different cytosine residues, for testing patterns of DNA methylation on gene expression, and for site-specific methylation, as well as methylated DNA constructs. Methods are provided that include steps of denaturing a circular double-stranded DNA construct; hybridizing primers to separate strands of the denatured circular DNA construct; contacting the hybridized primers with a DNA polymerase, deoxynucleoside triphosphates, and copies of the primers; contacting nicked copies with a DNA ligase so as to form a copy of the circular DNA construct; contacting the copy of the circular DNA construct with a methyltransferase enzyme; transfecting a cell with C-5 methylated circular DNA construct; and quantifying expression of a gene of interest, thereby determining the effect of C-5 methylating cytosine nucleotide residues of DNA on expression of the gene of interest.
