Doxycycline Hyclate is the hyclate salt form of a synthetic, broad-spectrum tetracycline antibiotic exhibiting antimicrobial activity. It is an antimicrobial tetracycline that acts as an inhibitor of a wide range of matrix metalloproteinases (MMPs) of MMP-1 and MMP-8. Doxycycline hyclate binds reversibly to the 30S ribosomal subunit, possibly to the 50S ribosomal subunit as well, thereby blocking the binding of aminoacyl-tRNA to the mRNA-ribosome complex. This leads to an inhibition of protein synthesis.

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.
