Description:
preQ1 is a precursor in the biosynthesis of queuosine, a bacterial nucleoside incorporated into tRNA by tRNA transglycosylase. preQ1 binds to an aptamer domain on tRNA that acts as a riboswitch to repress gene expression.
Handling:
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.
