Rabbit Monoclonal Antibody to Human Dickkopf 1 Homolog
DKK1 ( dickkopf related protein 1 ) is a head inducer secreted from the vertebrate head organizer and belongs to the DKK protein family including four members. DKK1 is synthesized initially as a precursor protein with an N-terminal signal peptide and two cysteine-rich domains. DKK proteins have distinct patterns of expression in adult and embryonic tissues and have effects on Wnt signaling implicated in diverse processes. Dkk1 is a specific and high-affinity ligand for LRP6 ( LDL-receptor-related protein 6 ) acting as a Wnt co-receptor. Dkk1 blocks LRP6-mediated Wnt/beta-catenin signaling by antagonistically inhibiting the formation of Wnt-Fz-LRP6 complex which triggers the Wnt signal pathway. It is revealed that Wnt signaling in osteoblasts is necessary to promote BMP-2-mediated differentiation of pre-osteoblast cells, and therefore, DKK1 may play a key role in regulating pre-osteoblast differentiation and the development of multiple myeloma-associated osteolytic bone lesions.
Human Dkk1 / Dickkopf-1. No cross-reactivity with human cell lysate ( 293 cell line ) in WB and ELISA.
Recombinant human Dkk1 protein
Western blot: This antibody can be used at 1 - 2 μg/mL with the appropriate secondary reagents to detect human Dkk1 in WB. Using a DAB detection system, the detection limit for Dkk1 is approximately 1 ng/lane under non-reducing conditions. Use of this antibody under reducing conditions is not recommendedELISA: This antibody can be used at 0.1 - 0.2 μg/mL with the appropriate secondary reagents to detect human Dkk1. The detection limit for human Dkk1 is approximately 0.00975 ng/well
This antibody was obtained from a rabbit immunized with purified, human cell-derived, recombinant human dickkopf related protein 1.
