Human IGFBP-6 Antibody Summary

Species Reactivity

Human

Specificity

Detects human IGFBP-6 in direct ELISAs. In direct ELISAs, approximately 20% cross-reactivity with recombinant mouse (rm) IGFBP-6 is observed, less than 4% cross-reactivity with rmIGFBP-3 and recombinant human (rh) IGFBP-4 is observed, and no cross-reactivity with rhIGFBP‑1, -2, -3, rmIGFBP-1, or -2 is observed.

Source

Monoclonal Mouse IgG_2B Clone # 164428

Purification

Protein A or G purified from hybridoma culture supernatant

Immunogen

Mouse myeloma cell line NS0-derived recombinant human IGFBP-6
Ala25-Gly240
Accession # P24592

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Applications

Recommended Concentration

Sample

Neutralization

Measured by its ability to neutralize IGFBP‑6 inhibition of IGF‑II-dependent proliferation in the MCF‑7 human breast cancer cell line. Karey, K. P. et al. (1988) Cancer Research 48:4083. The Neutralization Dose (ND₅₀) is typically 5‑25 µg/mL in the presence of 0.8 µg/mL Recombinant Human IGFBP‑6 and 14 ng/mL Recombinant Human IGF‑II.

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.

IGFBP‑6 Inhibition of IGF‑II-dependent Cell Proliferation and Neutralization by Human IGFBP‑6 Antibody. Recombinant Human IGFBP-6 (Catalog # 876-B6) inhibits Recombinant Human IGF-II (Catalog # 292-G2) induced proliferation in the MCF-7 human breast cancer cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human IGF-II (14 ng/mL) activity elicited by Recombinant Human IGFBP-6 (0.8 µg/mL) is neutralized (green line) by increasing concen-trations of Mouse Anti-Human IGFBP-6 Monoclonal Antibody (Catalog # MAB8762). The ND₅₀ is typically 5-25 µg/mL.

Background: IGFBP-6

The superfamily of insulin-like growth factor (IGF) binding proteins include the six high-affinity IGF binding proteins (IGFBP) and at least four additional low-affinity binding proteins referred to as IGFBP related proteins (IGFBP-rP). All IGFBP superfamily members are cysteine-rich proteins with conserved cysteine residues, which are clustered in the amino- and carboxy-terminal thirds of the molecule. IGFBPs modulate the biological activities of IGF proteins. Some IGFBPs may also have intrinsic bioactivity that is independent of their ability to bind IGF proteins. Post-transitional modifications of IGFBP, including glycosylation, phosphorylation and proteolysis, have been shown to modify the affinities of the binding proteins to IGF. Human IGFBP-6 cDNA encodes a 240 amino acid (aa) precursor protein with a putative 24 aa signal peptide that is processed to generate the 216 aa mature protein that is O-glycosylated. IGFBP-6 is expressed in ovarian cells, prostatic cells, and fibroblasts. IGFBP-6 is found predominantly in CSF and serum. IGFBP-6 binds preferentially to IGF-II, exhibiting a 2-fold higher affinity for IGF-II than for IGF-I.
