Active Recombinant Human EGFR Protein (Leu 25 - Ser 645), Fc-tagged

• Cat.No.: EGFR-339H
• Product Overview: Recombinant Human EGFR Protein, Fc-tagged is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Ser 645 (Accession # NP_005219). Predicted N-terminus: Leu 25. This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 95 kDa. The protein migrates as 130-140 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  Recombinant Human EGFR Protein, Fc-tagged at 1 μg/mL (100 μL/well) can bind Cetuximab with a linear range of 0.1-2 ng/mL (Routinely tested).
• Molecular Mass: 95 kDa
• Protein length: Leu 25 - Ser 645
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Notes: Please avoid repeated freeze-thaw cycles.
• Stability: No activity loss is observed after storage at:
  4-8 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.

Reviews

09/05/2022

The powerful biological activity of EGFR combined with its high purity makes the experimental results highly reproducible, which is of great significance in the field of scientific research.

09/26/2019

Due to the short half-life and high clearance characteristics of EGFR, they can better adapt to the needs of clinical treatment and provide more treatment options for patients.

03/23/2019

The production process of EGFR uses advanced biotechnology, which makes the production process more efficient and environmentally friendly, and reduces the consumption of human and material resources.

Q&As

What biological processes of human embryonic development and tissue regeneration is EGFR associated with?

It is associated with biological processes in human embryonic development and tissue regeneration.

Why does EGFR-inhibiting drug therapy have adverse reactions?

EGFR inhibits adverse drug reactions such as rash, inflammation, and diarrhea during drug treatment.

What is the role of EGFR in tumor treatment?

The role of EGFR in tumor treatment is to act as a molecular marker and can be used as a prognostic indicator and monitor tumor progression; at the same time, EGFR mutations can also be targeted for targeted therapy.

What are the general methods used for EGFR gene mutation testing?

EGFR gene mutation detection generally uses PCR, fluorescence in situ hybridization, and direct sequencing.

What other drugs can EGFR inhibitors be combined with to increase efficacy?

The combination of EGFR inhibitors with chemotherapy drugs, radiotherapy, immunotherapy, etc. can increase the efficacy of treatment and reduce the occurrence of adverse reactions.

How do EGFR mutations affect the efficacy of targeted therapies?

EGFR mutations can have a significant impact on the efficacy of targeted therapies, and patients with mutations have higher response rates.
