Direct sequencing of PCR products in agarose gel slices.
Direct DNA sequencing of amplified polymerase chain reaction (PCR) products offers several advantages over cloning of amplified DNA products. It is faster (1 day versus 3—5 days) and in DNA samples containing sequence polymorphisms both the normal and mutated sequence can be detected in the same sequencing reaction. The major problems encountered in direct sequencing of amplified DNA have been ...
متن کاملDirect single stranded sequencing from agarose of polymerase chain reaction products.
The polymerase chain reaction (PCR) has made possible the rapid isolation and amplification of specific DNA segments, which can then be used for a wide range of applications (1). Direct sequencing of PCR products has been described, using assymetric PCR, which requires purification of the PCR product, or inclusion of 10% DMSO in the sequencing reaction (2, 3, 4). However, these methods of seque...
متن کاملBacteriophage T7 DNA polymerase – sequenase
An ideal DNA polymerase for chain-terminating DNA sequencing should possess the following features: (1) incorporate dideoxy- and other modified nucleotides at an efficiency similar to that of the cognate deoxynucleotides; (2) high processivity; (3) high fidelity in the absence of proofreading/exonuclease activity; and (4) production of clear and uniform signals for detection. The DNA polymerase...
متن کاملThermo Sequenase DNA polymerase and T. acidophilum pyrophosphatase: new thermostable enzymes for DNA sequencing.
A combination of thermostable enzymes has been developed that produces higher quality cycle sequences. Thermo Sequenase DNA polymerase is a thermostable enzyme engineered to catalyze the incorporation of ddNTPs with an efficiency several thousandfold better than other thermostable DNA polymerases. Since the enzyme also catalyzes pyrophosphorolysis at dideoxy termini, a thermostable inorganic py...
متن کاملGrafting of Acrylamide to Low Density Polyethylene During Melt Processing
Acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. Effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. FTIR studies revealed that the degree of grafting increased by an increase in acrylamide concentration. Maximum grafting was obtained at 7 mi...
