表达区间及表达系统（Source）
Human Glypican 3, His Tag, premium grade (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
It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

蛋白结构（Molecular Characterization）
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 30 kDa, 40 kDa and 65-80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 0.01 EU per μg by the LAL method.
无菌（Sterility）
Negative
支原体（Mycoplasma）

背景
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.
