| Small interfering
RNAs (siRNAs) are double stranded RNAs that the mediators of mRNA
degradation in the process of RNA interference (RNAi). RNAi has been used as
a tool to study gene functions (for a review, see Sharp 2001, Genes Dev 15:
485-490). The siRNA appears that longer dsRNA is processed into 21-23 nt
dsRNA (siRNA) by an enzyme, Dicer (Bernstein et al. 2001, Nature 409:
363-366; Knight SW and Bass BL 2001, Science 2: 2269-2271). Spring's
Knock-down siRNA Kit provides every things you need for generation of siRNAs
from the DNA fragment of target genes. Customers who have the constructs of
target genes in vectors containing any two of the promoters, T7, T3, and/or
SP6 at the 5'-end and 3'-end of inserted gene can directly generate siRNAs
with this kit within one day.
