DNA Polymers

Polydeoxynucleotides (DNA polymers) manufactured by Midland are prepared from high-purity deoxynucleoside triphosphates and specific polymerizing enzymes (terminal deoxynucleotidyl transferase or DNA polymerase). We use only DNA modifying enzymes produced in our laboratory to synthesize our polymers. DNA polymers are packaged on the basis of A260 units (U).

We have a long history of purifying DNA-polymerizing enzymes from natural sources to remove nucleases that compete with the synthetic reaction. We have thus enjoyed a reputation for polymers of greater length than those produced by our competitors. Each lot of polymer is analyzed by gel electrophoresis to estimate the range of sizes and degree of polydispersity. A certificate of analysis is provided with each polymer.

These names for DNA Polymers are included on this page for reference purposes: ( Polydeoxynucleotide, Polydeoxyadenylic, Polydeoxycytidylic, Polydeoxyguanylic, Polydeoxyguanylate, Poly dG, Polydeoxythymidylic, Polydeoxyinosinic, Polydeoxyuridylic, Polydeoxy ).
