Specification

• Source: Baculovirus-Insect Cells
• Species: Human
• Preparation method: Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation and then centrifuged to clarify the lysate. The cell lysate was boiled for 5 minutes in 1 x SDS sample buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
• Lysis buffer: Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF
• Quality control Testing: 12.5% SDS-PAGE Stained with Coomassie Blue
• Recommended Usage: 1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200μL pure water and boiled for 2-5 min.3. Store it at -80°C. Recommend to aliquot the cell lysate into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.Notes:The lysate is ready to load on SDS-PAGE for Western blot application. If dissociating conditions are required, add reducing agent prior to heating.
• Stability: Samples are stable for up to twelve months from date of receipt at -80°C
• Storage Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF
• Storage Instruction: Lysate samples are stable for 12 months from date of receipt when stored at -80°C. Avoid repeated freeze-thaw cycles. Prior to SDS-PAGE fractionation, boil the lysate for 5 minutes.
• Tag: Non
• Protein length: 730-1065

Q&As

What are the potential side effects of targeting ERBB3 in cancer therapy?

Potential side effects may include skin rash, diarrhea, and cardiovascular issues, as seen with other drugs targeting the EGFR family.

How does ERBB3 contribute to resistance to certain cancer therapies?

ERBB3 activation has been associated with resistance to some targeted therapies, such as EGFR inhibitors, making it a challenging target in cancer treatment.

How does ERBB3 interact with other receptors in the EGFR family?

ERBB3 can form heterodimers with other EGFR family members, such as EGFR and HER2, leading to the activation of downstream signaling pathways.

Can ERBB3 be used as a biomarker for prognosis in cancer patients?

Yes, elevated ERBB3 expression has been linked to poor prognosis in certain cancers, serving as a potential biomarker for patient outcomes.

In which types of cancers is ERBB3 commonly overexpressed?

ERBB3 overexpression is frequently observed in breast, ovarian, and gastric cancers, among others.
