Will be supplied as "Dideoxy-TTP, Na, Sequencing Grade, Solution". Unit of measure is "μmol".
For consistent performance in sequencing applications and primer extension reactions, use dideoxyribonucleotides from the leading manufacturer of nucleotides.
ddTTP, Sequencing Grade, is supplied in sealed and CO2-proof bottles to ensure a stable pH during shipment on dry ice. The pH is adjusted to match conditions for amplification.
ddTTP, Sequencing Grade, in dNTP mixes acts as chain terminator in sequencing and primer extension reactions. The high purity and carefully designed manufacturing process are ideally suited for the manufacturing of in vitro diagnostics.
