The performance of Alkaline Phosphatase conjugates diminishes over time. There are a number of factors that contribute to this loss of performance including (i) inactivation of the enzyme, (ii) instability of the bond which links Alkaline Phosphatase to the antibody, (iii) microbial attack and (iv) denaturation of the antibody. Loss of performance accelerates with increasing temperature and with increasing dilution of conjugate. For these reasons Alkaline Phosphatase conjugates are often kept in a concentrated form at 4C. LifeXtend conjugate stabilizer/diluent is a proprietary multi-component reagent system that protects antibody-Alk Phos conjugates from all of the negative factors noted above, thus ensuring the best possible performance in experiments performed at room temperature. Moreover, the ability to store Alkaline Phosphatase conjugates at working concentration eliminates waste and improves consistency from experiment to experiment. In addition to its proprietary enzyme stabilizers, LifeXtend contains antimicrobial agents as well as blockers to enhance signal to background in immunoassay applications.
