2.Do you have a special ID or catalog number for this item?

Very nice to receive your inquiry. The replies for your questions are as below.
1. What are the recommended storage conditions?
The recommended storage buffer is Tris-based buffer, 50% glycerol. For short-term storage, store at 4℃. For long-term storage, store at -20℃ or -80℃.
2. Do you have a special ID or catalog number for this item?

  • 功能:
    Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. It can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates CTNNB1 at 'Ser-45'. May phosphorylate PER1 and PER2. May play a role in segregating chromosomes during mitosis
