表达区间及表达系统(Source)

Human Glypican 3 (S359F), His Tag, low endotoxin (GP3-H5223) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - His 559 (Accession # P51654-1 (S359F)).

Predicted N-terminus: Gln 25

蛋白结构(Molecular Characterization)

Online(Gln 25 - His 559) P51654-1 (S359F)

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 61.7 kDa. The protein migrates as 66-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 0.1 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

CAR阳性表达率检测(Evaluation of CAR expression )

FACS Analysis of Anti-GPC3 CAR Expression

CAR

293 cells were transfected with anti-GPC3-scFv and RFP tag. 2e5 of the cells were first stained with B. Human Glypican 3 (S359F), His Tag, low endotoxin (Cat. No. GP3-H5223, 3 μg/mL) and C. His tag protein control, followed by FITC-conjugated anti-6xHis tag antibody. A. Non-transfected 293 cells and C. His tag protein control were used as negative control. RFP was used to evaluate CAR (anti-GPC3-scFv) expression and FITC was used to evaluate the binding activity of Human Glypican 3 (S359F), His Tag, low endotoxin (Cat. No. GP3-H5223).

Protocol

 

背景(Background)

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.
