Immunoglobulin E (IgE), Human Myeloma Plasma, Lambda

Cat. No.: np001078

GRADE & PURITY ≥95%(SDS-PAGE), Extinction Coefficient: 1.46

Overview

Frozen in 15 mM potassium phosphate, pH 7.4, with 150 mM NaCl and 0.05% NaN3.
IgE is the least abundant immunoglobulin in plasma, found at a concentration of less that 0.6 micrograms/ml of normal plasma. Elevated IgE levels are found in patients experiencing severe allergic reactions and parasitic infections. In a myeloma condition, IgE is produced by a single clone of plasma cells. The structure of myeloma IgE, however, is normal, and the immunoglobulin purified from a myeloma source is a useful protein for studying immunoglobulin behavior.
Prepared from human myeloma plasma, Lambda shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
