This cDNA synthesis system simplifies your work dramatically. All reaction components are premixed and lyophylised. You have to add your RNA and (for Your-Prime beads) the primer. Another advantage of the system is a little number of pipetting steps required, and therefore reduced risk of Rnase contamination and RNA degradation. - [Read First strand cDNA synthesis with Ready-To-Go Beads Protocol]

To target a specific mRNA for degradation, a portion of the mRNA target sequence must be known, and a segment of the target mRNA must be chosen that will be used for targeting by the cognate siRNA duplex. Protocol describes the selection of siRNA sequences for mammalian RNAi. - [Read Selection of siRNA Sequences for Mammalian RNAi Protocol]
Ascitic fluid from B-cell-derived tumors is an extremely concentrated solution of specific antibodies. Ascitic fluid is often stored at -70ÂșC to prevent proteolytic degradation. - [Read Storage of Ascitic Fluid Protocol]
Procedure describes how it denatures most of the modification and degradation proteins immediately giving the most accurate read out of the true levels of protein at the time of harvest. However, in cases where detection is a problem, a limited purification (e.g. isolation of nuclear extract for the detection of transcription factors) might be required to allow analysis. - [Read Western Blot Analysis of Endogenous Gene Expression Protocol]
3' Rapid Amplification of cDNA Ends RACE Using PCR Protocol. This protocol contains the steps for 3' end rapid amplification of mRNA by PCR. The first-strand cDNA is synthesized from total or poly(A+) RNA by priming from the poly-A tail of the mRNA using a oligo (dT) adaptor primer. The cDNA is then amplified via PCR using a gene-specific primer and an adaptor primer.
