IGFBP-3, CF, Mouse, Recombinant

Recombinant, mouse insulin-like growth factor binding protein 3 (IGFBP-3) consisting of amino acids 22-291 and expressed in NS0-derived murine myeloma cells with four substitutions: Arg250Gln, Gln259Arg, Ser260Gly, Arg271Pro. Mouse IGFBP-3 cDNA encodes a 291 amino acid residue precursor protein with a putative 27 aa residue signal peptide.

ED₅₀ = 0.125-0.5 µg/ml as measured by inhibition of the biological activity of IGF-I or IGF-II (30 ng/ml) on MCF-7 human breast adenocarcinoma cells.

Toxicity: Standard Handling (A)

Lyophilized from 0.2 µm filtered Acetonitrile, TFA.

Following reconstitution refrigerate (4°C) for short-term storage or aliquot and freeze (-20°C) for long-term storage. Stock solutions are stable for up to 1 month at 4°C or for up to 3 months at -20°C.

Reconstitute to 100 µg/ml in sterile PBS.
