Problems with gene knockdown

... assay and made virus with them. The virus / plasmid has an antibiotic resistance gene which is expressed under the same promoter control ( mir30 motif). shRNAs were tested against both rat and mouse cDNAs in luciferase assay. The infected cells (in both rat and mouse cell lines) were selected ...

I need immediate help!! How to PCR primer designing?

... GenBank. Conserved regions were identified by using software Clustal X/W. Than primer A was designed based on the conserved amino acid sequence motif DD(T/I)(I/Y/F)D(A/V)Y(A/G). The sequence of sense primer A was 5’-GA(C/T) GA(C/T) III T(T/A)(T/C) GA(C/T) GCI (C/T)A(C/T) GG-3’. My question is ...

How to find motif frequencies

... yeast gene using seceral data sources. I know that gene can be clustered using gene expression data and using other alternatives. I klnow that motif frequencies is also a nother solution. I have read in a paper that using frequency measure of motifs we can cluster genes. Can anyone tell me ...

Re: Conservative region of a gene

... reasons why knowing whether a SNP is in a conserved region could be useful. First, conserved regions are likely to encode a useful functional motif of a protein. Evolutionary theory suggests that conserved regions vary less because their sequence is selected for by natural selection. Think ...
