Biotin phosphoramidite stands as a vital instrument for incorporating biotin labels into oligonucleotide sequences, enabling the efficient labeling of oligonucleotides. Biotin phosphoramidite features a spacer arm composed of 15 atoms. This spacer arm is designed to minimize potential hindrances associated with biotin binding. It complements the commonly used biotin phosphoramidite, which lacks the DMT group. The latter can only be added to the 5'- end of the oligonucleotide, and its addition effectively terminates the synthesis process.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
