The protein encoded by this gene is a regulatory proteininvolved in mitosis. The gene product complexes with p34(cdc2) toform the maturation-promoting factor (MPF). Two alternativetranscripts have been found, a constitutively expressed transcriptand a cell cycle-regulated transcript, that is expressedpredominantly during G2/M phase. The different transcripts resultfrom the use of alternate transcription initiation sites. [providedby RefSeq].

Titration of the Cyclin B1 antibody may be required due to differences in protocols and secondary/substrate sensitivity.

A portion of amino acids 241-268 from the human protein was used as the immunogen for this Cyclin B1 antibody.

Aliquot the Cyclin B1 antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
