Scientific Data Images for Human LIF Biotinylated Antibody

Human LIF ELISA Standard Curve.

Recombinant Human LIF protein was serially diluted 2-fold and captured by Mouse Anti-Human LIF Monoclonal Antibody (Catalog # MAB2502) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human LIF Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF250) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Applications for Human LIF Biotinylated Antibody

Application
Recommended Usage

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human LIF Monoclonal Antibody (Catalog # MAB2502).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human LIF DuoSet ELISA Kit (Catalog # DY7734-05) for convenient development of a sandwich ELISA.

Background: LIF

LIF is a 36‑67 kDa highly glycosylated polypeptide (1, 2) produced by a variety of cells including T cells (3), monocytes (4), fibroblasts (5), osteoblasts (6) and mast cells (7). Consistent with its many synonyms, LIF exhibits a broad spectrum of effects on both hematopoietic and nonhematopoietic cells. For example, LIF inhibits the differentiation of embryonic stem cells (8), up regulates the synthesis of acute phase proteins in hepatocytes (9), down regulates lipoprotein lipase activity in adipocytes (10), and preferentially induces a cholinergic phenotype in sympathetic neurons (11). The receptor for LIF (LIF R) has been isolated and found to be a 190 kDa type I transmembrane glycoprotein (12). Although this molecule binds LIF, the resultant LIF-LIF R complex is not sufficient to transduce an intracellular signal. This capability is provided by a 130 kDa signal transducing subunit (gp130) that is common to the functional receptors for IL-6, IL-11, CNTF, and Oncostatin M (13, 14). Since gp130 is a ubiquitously expressed membrane protein, the presence of LIF R (membrane-bound or soluble form) ultimately determines the cell’s responsiveness to LIF. Cells known to express LIF R include osteoblasts (6), hepatocytes (15), macrophages (15), neurons (5), and megakaryocytes (16). Human and mouse LIF exhibit 78% sequence homology, and human LIF is biologically active on mouse cells.
