ClickTech Library Kit full-length mRNA_Seq

Based on its unique and proprietary click technology, baseclick has developed a long read/ full length NGS kits with superior performance. These kits solve the problems of todays conventional long read/full length library kits thanks to the novel click tech ligation.

Today: In RNA Library Kits enzymatic ligation is a limiting step , delivers only max. 40% efficiency and causes mayor problems

Mutations of exonic splicing enhancers motifs are significant contributors to genetic disorders.

Problem1

Simple point mutations can Inhibit affinity for splicing factors and alter alternative slicing, leading to altered mRNA sequences and protein translation.

Todays conventional RNA library kits are not able to detect this alternative splicing

Problem 2

Randomized primers lead automatically to a statistical cDNA length distribution and to a main problem of analytical software. The rates of aberrant and pre- mRNA splicing can not be evaluated at the nucleotide level to determine the quantity and identify of these events across splicing junctions.

Todays conventional RNA Library kit use solely randomized primers and therefore are not able to identify each artifact and where the aligned reads differ from reference genomes.

Problem 3

In order to give complete diagnostic information to the end user it is inevitable to have full length information from 5´End to 3´ End eg for cancer tissues.

Todays conventional RNA library kits do not reverse transcribe the complete cDNA significantly from the 3´End to the 5´End especially the very important 5´End is inaccessible for these kits.

NEW: ClickTech Ligation makes the difference in full length RNA Library kits, has no limits and delivers up to 95% click efficiency

baseclick’s ClickTech Library Kit full – length mRNA Seq has been developed for e.g sequencing of total mRNA or the whole exome of cells for genetic diagnosis. The kit provides reagents for cDNA synthesis of any RNA pool and introduces a single clickable nucleotide at the 3’End of cDNA. This azide modified single stranded cDNA can react with alkyne-adapter sequence in a highly selective fashion under benign click reaction conditions yield 95%. With the included special designed primer, the adapter clicked single stranded cDNA can be use for PCR amplification of the cDNA pool as such or for targeted genes amplification. Sanger Sequencing of specific sequences achieved a high accuracy of 99.999% certainty.
