Geminin is a protein that inhibits DNA replication by preventing the loading of MCM complex on chromatin. Human CDT1 is a 65kDa protein that contains 546 amino acids and coimmunoprecipitates with Geminin. Inhibition of DNA replication by Geminin in cell-free cDNA replication extracts can be reversed by the addition of excess CDT1. In the normal cell cycle, CDT1 is present only in G1 and S phases, whereas Geminin is present in S and G2 phases.
Applications:
Suitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.
Recommended Dilution:
Western Blot: 1:1000-1:2500
Immunoprecipitation: 2-5ug/mg lysate
Immunohistochemistry (paraffin): 1:100-1:500. Requires heating in citrate buffer, pH 6 for antigen retrieval.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
