Oligonucleotides are short stretch of single stranded DNA or RNA molecules used in genetic testing, research and forensic. These are chemically synthesized and has got applications in polymerase chain reaction (PCR),DNA sequencing etc.
Length of oligonucleotide is denoted as '-mer' for example : 18-mer, 22-mer, etc.
Nucleic acid synthesis columns come in several scales, which are a function of the amount of the 3' nucleoside coupled to the support material. Popular column sizes Oligonucleotide Synthesis
range from 40 nmol to 10umol. Popular support materials include controlled-pore glass (CPG) and polystyrene. The CPG columns are typically supplied having pore sizes of either 500 A or 1000 A. The scale of column used for a synthesis depends on both the quantity and the length of oligonucleotide desired. The greater the amount of 3' nucleoside attached to the column support, the greater the yield of oligo. Polystyrene or large-pore CPG columns are recommended for oligonucleotides greater than 50.
oligonucleotides are synthesized at different scales like 0.05umol, 0.2umol, 1umol, etc. depending on the application it is used for.
The number of micromoles of an oligonucleotide synthesized on a column, therefore, can be calculated by multiplying the length of the oligonucleotide by the column scale.
A good explanation on calculation of oligonucleotide Yield, Resuspension, and Storage
