Protein A or G purified from hybridoma culture supernatant
Human embryonic kidney cell line HEK293-derived recombinant human IGFLR1 Met1-Pro163 Accession # Q9H665
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
0.25 µg/106 cells
Blockade of Receptor-ligand Interaction
In a functional ELISA, 0.05-0.3 μg/mL of this antibody will block 50% of the binding of 10 ng/mL of rhIGFL-1 to immobilized rhIGFLR1 coated at 100 ng/mL (100 μL/well). At 10 μg/mL, this antibody will block >90% of the binding.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Insulin Growth Factor-like Family Receptor 1 (IGFLR1) is a 355 amino acid (aa) type 1a transmembrane protein that was identified in a screen for binding partners of human IGFL-1 (1). Mature human IGFLR1 consists of an extracellular domain (ECD) with two putative cysteine-rich domains (CRDs), a transmembrane region, and a cytoplasmic domain (1). Its structure has similarities to TNF receptor family members (1). Over the first 163 aa, human IGFLR1 shares 61% and 59% aa sequence identity with mouse and rat IGFLR1, respectively. In mice, IGFLR1 is expressed primarily on T cells and, similar to the human proteins, mouse IGFLR1 binds the mouse IGFL protein (1). Human IGFL-1 expression is enhanced by TNF-alpha treatment and was shown to be up-regulated in human psoriatic skin samples, suggesting that IGFLR1 may have a role during skin inflammation (1).
