分子别名(Synonym)

CA125,CA-125,CA125MUC-16,FLJ14303,MUC16,mucin 16,mucin-16

表达区间及表达系统(Source)

Biotinylated Human CA125, Fc,Avitag (CA5-H82F4) is expressed from human 293 cells (HEK293). It contains AA Gly 12660 - Met 12923 (Accession # Q8WXI7-1).

Predicted N-terminus: Gly 12660

蛋白结构(Molecular Characterization)

Online(Gly 12660 - Met 12923) Q8WXI7-1

This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).

The protein has a calculated MW of 56.9 kDa. The protein migrates as 75-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Biotin:Protein Ratio)

The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

存储(Storage)

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

This product is stable after storage at:

  1. -20°C to -70°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Biotinylated Human CA125, Fc,Avitag (Cat. No. CA5-H82F4) SDS-PAGE gel

Biotinylated Human CA125, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human Mesothelin, His Tag (Cat. No. MSN-H5223) at 10 μg/mL (100 μL/well) can bind Biotinylated Human CA125, Fc,Avitag (Cat. No. CA5-H82F4) with a linear range of 2-78 ng/mL (QC tested).

Protocol

背景(Background)

The CA125, also known as the MUC16, is a mucin protein that may be found in type I transmembrane or secreted forms that are used monitor the progress of epithelial ovarian cancer therapy. The CA 125 molecule is almost certainly a glycoprotein with a predominance of O-linkages. It is heterogeneous with regard to both size and charge, most likely due to continuous deglycosylation of side chains during its life-span in bodily fluids. It exists as a very large complex (perhaps as much as 4 million daltons) under natural conditions.
