Extra Details:
This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. MCM2, also called DNA replication licensing factor MCM2, Minichromosome maintenance protein 2 homolog or Nuclear Protein BM28) is one of the highly conserved mini-chromosome maintenance proteins (MCM) that are involved in the initiation of eukaryotic genome replication. The hexameric protein complex formed by MCM proteins is a key component of the pre-replication complex (pre-RC) and may be involved in the formation of replication forks and in the recruitment of other DNA replication related proteins. This protein forms a complex with MCM4, 6, and 7, and has been shown to regulate the helicase activity of the complex. This protein is phosphorylated, and thus regulated by protein kinases CDC2 and CDC7. Double serines at positions 26 and 27 are conserved in rat and mouse. High homology >88% to similar proteins from several other species. Expected broad reactivity to various lysates.
Formulation:
0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2
Host:
Rabbit
Immunogen:
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an N-Terminal region near amino acids 15-40 of human MCM2 protein.
Isotype:
IgG
Physical State:
Liquid
Reactivities:
Human
Shipping Conditions:
Dry Ice
Specificity:
This affinity-purified antibody is directed against human MCM2 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification. Approximately equivalent reactivity occurs against both unphosphorylated and phosphorylated forms of human MCM2 (phosphorylated at residues pS26 and pS27). A BLAST analysis was used to suggest cross reactivity with MCM2 proteins from
Storage Conditions:

Antibody: Polyclonal Antibody
Western blot using Rockland's Affinity Purified anti-MCM2 antibody shows detection of both phosphorylated and unphosphorylated MCM2 present in nuclear extracts from elutriated human cells (MO59K/K562). The MCM2 protein is phosphorylated after initiation of DNA replication, therefore, the protein is unphosphorylated in early S phase, and gradually becomes phosphorylated throughout S phase. In G2/M, all MCM2 is phosphorylated. Panel A shows western blot results for lysates were prepared from asynchronous cells (lane 1), cells arrested in early S with aphidicolin (lane2), and cells arrested in mitosis with nocodazole (lane 3). Panel B shows a schematic diagram of bands representing phosphorylated and unphosphorylated MCM2 present in these preparations. Asynchronous cells contain a doublet of both forms. Aphidicolin treated cells contain only unphosphorylated MCM2 and nocodazole treatment results in only phosphorylated MCM2 detected in the lysate. The phosphorylated band migrates faster than the unphosphorylated form and is seen as the lower band. There is a clear switch from the unphosphorylated form in the center lane, to the phosphorylated form in the third lane, confirming recognition of both forms of MCM2 by this antibody. The primary antibody was diluted 1:400 for this experiment. Personal Communication, Jennifer Seiler, NIH, CCR, Bethesda, MD.
