Technical Data
Kip2, p57 (p57Kip2, Cyclin-dependent Kinase Inhibitor 1C, CDKN1C, Cyclin-dependent Kinase Inhibitor p57)
p57 protein is a cyclin dependent kinase inhibitor similar to p21 and p27 proteins and acts as a tumor suppressor. The gene encoding for p57 is in a chromosome region that is a common site for loss of heterozygosity in certain diseases. This antibody will help detect p57 and may be useful in determining the functional significance of this protein in a variety of tissues.

Suitable for use in Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry: 1:50-1:100 for 1 hr at RT
Optimal dilutions to be determined by the researcher.

Positive Control:
