Human IgE (non-immune)(azide-free, low endotoxin)

Human Monoclonal Antibody


This product is purified human IgE with kappa light chains produced in vitro from a monoclonal hybridoma. Original material is obtained from a healthy donor tested negative by US-FDA approved tests against HIV, HCV and Hepatitis B.Must be handled as potentially infectious as all human material.The purity of the human IgE is > 90%, tested by SDS-PAGE.As the IgE comes from a monoclonal cell line, there is no contamination of antibodies of other isotypes. The human IgE is purified by Protein L chromatography. The remaining contaminants are mainly components from Foetal Bovine Serum.








100 µl, 1mg/mL

Protein L purified. Endotoxin level < 25 EU/mg.
0.01 M phosphate buffer, pH 7.4, with 0.15 M NaCl
For long term storage, -18 to -22ºC is recommended, but it may be stored for short term use at 2 to 8ºC. The expiry date refers to storage at -18 to -22ºC. Repeated freeze/thawing is not recommended
