• Alternative names: (B-lymphocyte surface antigen B1) (Bp35) (Leukocyt
• Note: For research use only
• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein indeionized sterile water to a concentration of 0.1-1.0 mg/mL.Aliquot for long-term storage at -80℃. Solubilize for 60 minutes at room temperature with occasional gentle mixing. Avoid vigorous shaking or vortexing.
• Expiration Date: 6 months from date of receipt.

Western Blot is detected by Mouse anti-6*His monoclonal antibody.

Measured by its binding ability in a functional ELISA. Immobilized human CD20 at 2 μg/ml can bind Anti-CD20 recombinant antibody, the EC50 is 3.243-7.085 ng/mL.

The presence of VLP-like structures was confirmed by TEM

Based on the SEQUEST from database of Mammalian Cell host and target protein, the LC-MS/MS Analysis result could indicate that this peptide derived from Mammalian Cell-expressed Homo sapiens (Human) CD20.
