Tested Applications

• Positive WB detected in: A549 cells, human placenta tissue, Caco-2 cells
• Positive IHC detected in: human placenta tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:2000-1:10000
• Immunohistochemistry (IHC): IHC : 1:250-1:1000

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Insulin-like growth factor binding protein-3 (IGFBP-3) contains a 27 amino acid putative signal sequence followed by a mature protein of 264 amino acids with 18 cysteine residues clustered near the N- and C-terminus. Accordingly, expression of the cloned IGFBP-3 cDNA in mammalian tissue culture cells results in secretion of the protein into the culture medium. IGFBP-3 shares high homology (33% amino acid identity) including conservation of all 18 cysteine residues with a smaller human IGF-binding protein (BP-28) identified in amniotic fluid. IGFBP-3 has one or more glycosylation sites with a protein core of ∼30 kDa. Western blots revealed that the 39-45 kDa IGFBP-3 fragment is a glycoprotein.
