Human Phospho-Mer DuoSet IC ELISA Summary

Assay Type
Solid Phase Sandwich ELISA
96-well strip plate
Sample Volume Required
Cell lysates (100 µL)
Sufficient Materials
Kits available for two, five, or fifteen 96-well plates*
Please see the product datasheet

* Provided that the recommended microplates, buffers, diluents, substrates and solutions are used, and the assay is run as summarized in the Assay Procedure provided.

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure tyrosine-phosphorylated human Mer in cell lysates. An immobilized capture antibody specific for Mer binds both phosphorylated and unphosphorylated Mer. After washing away unbound material, a biotinylated detection antibody is used to detect only phosphorylated receptor, utilizing a standard HRP format.

Scientific Data

The Human Phospho-Mer DuoSet IC ELISA is more sensitive than immunoprecipitation (IP)-Western analysis NS0 cells transfected with human Mer (NS0-hMer) were treated with conditioned media from the human lung cell line, WI-38, for 15 minutes to induce tyrosine phosphorylation of Mer. Lysates were serially diluted and analyzed by (A) IP-Western blot and (B) this DuoSet IC ELISA. IPs were done using an anti-Mer monoclonal antibody and goat anti-mouse agarose. Immunoblots were incubated with an HRP-conjugated anti-phosphotyrosine monoclonal antibody (R&D Systems, Catalog # HAM1676) to detect phospho-Mer. Bands were visualized by chemiluminescent detection using WesternGloTM Chemiluminescent Detection Substrate (R&D Systems, Catalog # AR004). Human Phospho-Mer can be detected in this DuoSet IC ELISA by using approximately 5 to 10 times less lysate than is needed for a conventional IP-Western blot.

The Human Phospho-MerDuoSet IC ELISA detects ligand-induced Mer tyrosine phosphorylation NS0-hMer cells were untreated or treated with conditioned media from the human lung cancer cell line, WI-38, for 15 minutes. ELISA and IP-Western blot (inset) analyses were done using 100 μg and 400 μg of lysate, respectively. IP-Western blots for phospho-Mer (p-Mer) were done as described in Figure 1. Blots were stripped and total Mer was detected using a biotinylated anti-Mer polyclonal antibody (R&D Systems, Catalog #BAF891).

The specificity of the Human Phospho-MerDuoSet IC ELISA is confirmed by receptor competition NS0-hMer cells were treated with conditioned media from the human lung cell line, WI-38, for 15 minutes minutes. The indicated amounts of recombinant extracellular domains of human Mer/Fc (R&D Systems, Catalog #891-MR), human Axl/Fc (R&D Systems, Catalog #154-AL), human Dtk/Fc (R&D Systems, Catalog #859-DK) or human TrkA/Fc (R&D Systems, Catalog #175-TK) were added to 100 μg lysate and analyzed using this DuoSet IC ELISA. Competition was observed only with recombinant human Mer.

Background: Mer

Axl (Ufo, Ark), Dtk (Sky, Tyro3, Rse, Brt) and Mer (human and mouse orthologs of chicken c-Eyk) constitute the TAM receptor tyrosine kinase subfamily. This RTK subfamily is characterized by an extracellular domain that consists of two Ig-like motifs and two fibronectin type III motifs. These receptors bind the vitamin K-dependent protein Growth Arrest Specific Gene 6 (Gas6). Receptor activation leads to cell proliferation, migration, or the prevention of apoptosis. Cellular signaling through this family of RTKs is involved in hematopoiesis, embryonic development, tumorigenesis, and spermatogenesis.
