• Species Reactivity

  Mouse

• Specificity

  Detects mouse DPPA5/ESG1 in direct ELISAs and Western blots. In Western blots, approximately 25% cross-reactivity with recombinant human DPPA5 is observed and approximately 10% cross-reactivity with recombinant mouse DPPA4 is observed.

Background: DPPA5/ESG1

DPPA5, also known as Esg-1 and ECAT2, is a 14 kDa RNA-binding protein expressed in early embryos, primordial germ cells, and embryonic stem cells and is used as a marker of the pluripotent state. Mouse DPPA5 is 118 amino acids in length and shows 63% amino acid identity with human and 81% amino acid identity with rat DPPA5 proteins.

• Long Name:

  Developmental Pluripotency Associated 5

• Entrez Gene IDs:

  340168 (Human); 434423 (Mouse); 301101 (Rat)

• Alternate Names:

  developmental pluripotency associated 5; developmental pluripotency-associated 5 protein; DPPA5; embryonal stem cell specific gene 1; Embryonal stem cell-specific gene 1 protein; ESG1; ESG1ESG-1; hDPPA5
