• Specificity

  Detects chicken Caronte in direct ELISAs and Western blots. In direct ELISAs, approximately 15% cross-reactivity with recombinant human (rh) Cerberus-1 is observed and less than 1% cross-reactivity with rhDAN and recombinant mouse Gremlin is observed.

• Blockade of Receptor-ligand Interaction

  In a functional ELISA, 1.5-6 µg/mL of this antibody will block 50% of the binding of 100 ng/mL of Recombinant Human BMP-4 (Catalog # ) to immobilized Recombinant Chicken Caronte Fc Chimera (Catalog # ) coated at 5 µg/mL (100 µL/well). At 30 μg/mL, this antibody will block >90% of the binding.

Background: Caronte

Chicken Caronte, the ortholog of mammalian Cerberus, is a member of the Cerberus/DAN family of secreted glycoproteins. There are at least 5 Dan Domain (DAND) family members including DAN (DAND1), Gremlin/Drm (DAND2), PRDC (Protein Related to Dan and Cerberus; DAND3), Cerberus (DAND4), and Coco (DAND5). Caronte is expressed in the left paraxial mesoderm and is the molecule responsible for transducing left-sided positional information from the node to the periphery of the lateral plate mesoderm (LPM) during chicken embryonic development. Caronte functions as a BMP antagonist, inducing Nodal and downstream genes in the LPM by interfering with the repressive activity of bilaterally-produced BMPs. In addition, antagonism of BMPs by Caronte induces the expression of the Lefty gene in the midline. Caronte binds both BMP-4 and BMP-7 in immunoprecipitation experiments. Recombinant chicken Caronte preparations from R&D Systems have been shown to bind BMP-4 in a functional ELISA and induce heart reversals in Xenopus embryos.
