To address these challenges, our next generation of strand-specific RNA library prep kits have been reformulated at each step, resulting in several fold higher yields of high quality libraries and enabling use of lower input amounts and fewer PCR cycles. Also, added information regarding cells isolated via enzymatic digestion of whole tissues. The entire workflow takes about 3 hours. Sequential 2X sparQ or SPRI purification of the ADT fraction after cDNA amplification reduces carryover of primers from cDNA amplification, and minimizes the amplification of this product during ADT-library amplification. Adjust cell concentration using PBS according to the input requirements of your single cell partitioning platform. 5-Methylcytosine (5mC) oxidases, the ten-eleven translocation (TET) proteins, initiate DNA demethylation, but it is unclear how 5mC oxidation is regulated.

Reverse transcription quantitative polymerase chain reaction (RT-qPCR) assays were run on the StepOnePlus system (Applied Biosystems) using the KAPA SYBR FAST qPCR Kit (Kapa Biosystems) according to the manufacturerâs instructions, and data were analyzed by StepOne software v2.2.2. qPCR was used to quantitate adaptor-ligated molecules, and quantitation values were then normalized to the conversion rate for Ultra II. No rights are granted for use of the product for Digital PCR or real-time PCR applications, with the exception of quantification in Next Generation Sequencing workflows. Protein and RNA expression can be then characterized in single cells, simultaneously. The phosphorothioate bonds in the primer renders the oligonucleotide resistant to nuclease degradation. Figure 1.
