concentration :
100ug specific antibody in 200ul
storage stability :
Aliquot and store at -20 degree C. Minimize freezing and thawing.

Peptide ELISA (EIA)
app notes :
Peptide ELISA: Antibody detection limit dilution 1: 64000. Western Blot: Preliminary experiments gave an approx 26kDa band in human ovary and placenta lysates after 0.1ug/ml antibody staining. Please note that currently we cannot find an explanation in the literature for the band we observe given the calculated size of 17.9kDa according to NP_954980.1. The 26kDa band was successfully blocked by incubation with the immunizing peptide.

ncbi summary :
This gene encodes a protein that in mice may function as a maternal factor during the preimplantation stage of development. In mice, this gene may play a role in transcriptional repression, cell division, and maintenance of cell pluripotentiality. In humans, related intronless loci are located on chromosomes 14 and X.

uniprot summary :
DPPA3: Primordial germ cell (PGCs)-specific protein involved in epigenetic chromatin reprogramming in the zygote following fertilization. In zygotes, DNA demethylation occurs selectively in the paternal pronucleus before the first cell division, while the adjacent maternal pronucleus and certain paternally-imprinted loci are protected from this process. Participates in protection of DNA methylation in the maternal pronucleus by preventing conversion of 5mC to 5hmC: specifically recognizes and binds histone H3 dimethylated at 'Lys-9' (H3K9me2) on maternal genome, and protects maternal genome from TET3-mediated conversion to 5hmC and subsequent DNA demethylation. Does not bind paternal chromatin, which is mainly packed into protamine and does not contain much H3K9me2 mark. Also protects imprinted loci that are marked with H3K9me2 in mature sperm from DNA demethylation in early embryogenesis. May be important for the totipotent/pluripotent states continuing through preimplantation development. Also involved in chromatin condensation in oocytogenesis. Chromosomal Location of Human Ortholog: 12p13.31. Cellular Component: cytoplasm; female pronucleus; male pronucleus; nucleus. Molecular Function: methylated histone residue binding. Biological Process: chromatin modification; embryonic cleavage
