Gentaur Direct RT-PCR kit provides a fast and simple procedure for preparing first-strand cDNA directly from cultured cells without RNA purification. RNA in the lysate can be directly converted to cDNA and subsequently analyzed using the PCR reagents included in the kit or real-time RT-PCR kits purchased elsewhere. The whole process can be completed in less than 1.5 hours. Because no removal of genomic DNA is included in the protocol, users need to design primers from the exon-exon junctions of the target mRNA to allow detection of RNA only.
The performance of Gentaur Direct RT-PCR Kit is tested in an RT reaction using human embryonic kidney cell lysate with primer d(T)18. The sensitivity of the kit is verified by the detection of B2M transcript after 35 cycles. The length of cDNA achieved is verified by detection of a 248 bp by DNA agarose gel and DNA sequencing.
