Anti-Cetuximab Antibodies (Non-Neutralizing)

表达区间及表达系统(Source)

Mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with Cetuximab F(ab')2.

亚型(Isotype)

IgG1/kappa

特异性(Specificity)

Recognizes Cetuximab specifically, no cross reactivity with other humanized antibodies.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25mM Arginine, 150 mM 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.

No activity loss was observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 years under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Anti-Cetuximab Antibodies (Non-Neutralizing) (Cat. No. CEB-Y31) SDS-PAGE gel

Anti-Cetuximab Antibodies (Non-Neutralizing) 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

Anti-Cetuximab Antibodies bridging ELISA for Anti-Drug Antibody (ADA) assay development.Immobilized cetuximab at 1 µg/ml, added increasing concentrations of Anti-Cetuximab Antibodies (Cat. No. CEB-Y31, 10% human serum) and then added biotinylated cetuximab at 2 µg/ml. Detection was performed using HRP-conjugated streptavidin with a sensitivity of 39 ng/mL.

背景(Background)

Cetuximab is an epidermal growth factor receptor binding FAB. Cetuximab is composed of the Fv (variable; antigen-binding) regions of the 225 murine EGFr monoclonal antibody specific for the N-terminal portion of human EGFr with human IgG1 heavy and kappa light chain constant (framework) regions.
