Product Name:Trastuzumab (Anti-HER-2) Biosimilar In Vivo Antibody
Product Code:IVMB0215
Clone:4D5-8
Protein:HER-2/neu
Product Type:Biosimilar Recombinant Human Monoclonal Antibody
Synonyms:ErbB-2, NEU, NGL, HER2, TKR1, CD340, MLN 19, HER-2/neu
Isotype:Human IgG1κ
Reactivity:Human
Immunogen:Human epidermoid carcinoma cells (A431) over-expressing EGFR.
Applications:CyTOF®, ELISA, FC, IHC
Formulation:This biosimilar antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Endotoxin Level:< 1.0 EU/mg as determined by the LAL method
Purity:≥95% monomer by analytical SEC
Preparation:Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Storage and Handling:Functional grade biosimilar antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.
Applications:CyTOF®, ELISA, FC, IHC
Recommended Usage:FC
The suggested concentration for Trastuzumab biosimilar antibody for staining cells in flow cytometry is ≤ 0.25 µg per 106 in a volume of 100 µl. Titration of the reagent is recommended for optimal performance for each application.
Reactivity:Human
Specificity:This non-therapeutic biosimilar antibody uses the same variable region sequence as the therapeutic antibody Trastuzumab. Clone 4D5-8 recognizes human erbB-2. This product is for research use only.
Antigen Distribution:Ubiquitous expression with highest expression levels found in the kidney, skin, esophagus, and small intestine.
Immunogen:Human epidermoid carcinoma cells (A431) over-expressing EGFR.
Concentration:≥ 5.0 mg/ml
Endotoxin Level:< 1.0 EU/mg as determined by the LAL method

Trastuzumab is a monoclonal antibody targeting HER2, a 185 kDa transmembrane glycoprotein that contains an extracellular domain and intracellular tyrosine kinase activity. When it is functioning normally, the HER2 pathway supports cell growth and division. On the other hand, the over expression of HER2 propels cell growth beyond its typical range. This overexpression is associated with some cancers, namely breast and stomach, in which the HER2 protein can be expressed up to 100 times more than in typical cells. Trastuzumab induces an immune-mediated response that triggers the internalization and downregulation of HER2 making it an excellent target for immunotherapy. Several clinical studies are under way which show that anti-HER-2/neu antibodies inhibit the growth and proliferation of these tumor cells In vitro as well as In vivo.
