Biotin TEG CE Phosphoramidite is a valuable reagent for attaching biotin to both the 3' - end and 5' - end of oligonucleotides. This phosphoramidite is equipped with a 15 - atom mixed - polarity extended spacer arm based on a triethylene glycol linker. The extended spacer arm functions to physically separate the biotin moiety from the rest of the oligomer. This separation brings about several advantages that are particularly evident in practical applications. The distinct design of the spacer arm helps to optimize the performance of the biotin - labeled oligonucleotides, ensuring that the biotin's functionality is not compromised by the proximity of the oligomer structure.

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.
