Human Glypican 3, His Tag (GP3-H52H4) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - His 559 (Accession # P51654-1).
Predicted N-terminus: Gln 25 & Ser 359
This protein carries a polyhistidine tag at the C-terminus. This protein contains a furin-like convertase cleavage site, 355-RQYR-358, and will be partially processed into N and C-terminal fragment with calculated MW of 38.1 kDa and 24.6 kDa respectively. The protein migrates as 40 kDa, 32 kDa and 66-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 0.1 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Glypican-3 (GPC3) is also known as Intestinal protein OCI-5, GTR2-2, MXR7, which belongs to the glypican family. Glypican 3 / GPC-3 is highly expressed in lung, liver and kidney. Glypican-3 inhibits the dipeptidyl peptidase activity of DPP4. Glypican-3 may be involved in the suppression/modulation of growth in the predominantly mesodermal tissues and organs, and also may play a role in the modulation of IGF2 interactions with its receptor and thereby modulate its function.
