Bioactivity
(Glypican-3 (GPC3), a 70 kDa protein, is a member of the glypican family that attaches to the cell surface by a glycosylphosphatidylinositol anchor, is specifically up-regulated in hepatocellular carcinoma (HCC) although rarely or not expressed in normal liver tissues, making it a perfect test and treatment target for HCC. GPC3 is also a negative transcriptional regulator and tumor suppressor that inhibits the growth of breast, ovary, and lung cancer cells. It is reported that GPC3 can form a complex with insulin-like growth factor 2 (IGF2), and might thereby modulate IGF2 action. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human GPC3 and recombinant rat IGF2. Briefly, GPC3 was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to IGF2-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-GPC3 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody for 1h at 37 degree C, wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37 degree C. Finally, add 50 uL stop solution to the wells and read at 450/630 nm immediately. The binding activity of recombinant human GPC3 and recombinant rat IGF2 was shown in Figure 1, the EC50 for this effect is 0.08 ug/mL.)

Product Notes
The GPC3 gpc3 (Catalog #AAA161814) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Glypican 3 (GPC3) can be used in a range of immunoassay formats including, but not limited to, Activity Assay, Cell Culture. Researchers should empirically determine the suitability of the GPC3 gpc3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Thr343~His 559. It is sometimes possible for the material contained within the vial of "Glypican 3 (GPC3), Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening.
