Product Specific Information
Description
The monoclonal antibody IgE21 recognizes the immunoglobulin E class of antibodies. Like all immunoglobulins, IgE is expressed as a soluble molecule as well as a membrane bound form. IgE21 recognizes both forms.
This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer.
Applications Tested
This Ige21 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.2 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
Master mixes
• Master mixes of NFs should be made at 2-8 °C and may be made up to 4 hours ahead of time.
• We do not recommend storing master mixes containing NovaFluor conjugates overnight or longer.
Whole Blood compatibility
• When utilizing whole blood (as opposed to density-gradient-purified PBMC), we recommend lysing red blood cells in bulk prior to staining with NovaFluor conjugates.
• See the Bulk Lysis of Human Whole Blood protocol here.
• Staining of whole blood with NovaFluor conjugates followed by lysis of red blood cells may result in higher-than-expected background staining.
Viability dye compatibility
• NovaFluor dyes are not compatible with DNA intercalating viability dyes.
• Do not use viability dyes such as propidium iodide, 7-actinomycin D (7-AAD) and DAPI. Invitrogen LIVE/DEAD Fixable Dead Cell stains are recommended for use with NovaFluor dyes.
CellBlox Plus Blocking Buffer
• This NovaFluor conjugate comes with CellBlox Plus Blocking Buffer (Cat. No. C001T03F01), essential for optimal staining.
• Use CellBlox Plus Blocking Buffer in all experiments with NovaFluor conjugates.
• Add 5 µL per sample to antibody cocktails/master mixes (regardless of how many Novafluor-conjugated antibodies are present) before combining with cells.
• CellBlox Plus Blocking Buffer is compatible with either Super Bright Complete Blocking Buffer or Brilliant Stain Buffer and can be used in antibody cocktails/master mixes with those reagents.
• For single-color controls, use 5 µL of CellBlox Plus Blocking Buffer per 100 µL of cell sample (10^3 to 10^8 cells).
NovaFluor conjugates are based on Phiton technology utilizing novel fluorophore-containing nucleic acid dye structures that allow for engineered fluorescent signatures with consideration for spillover and spread impacts. Learn more

Target Information
IgE is one of the five classes of immunoglobulins found in mammals, characterized by its monomeric structure consisting of two heavy (epsilon) chains with four Ig-like constant domains and two light chains. Although IgE comprises only a small portion of the total immunoglobulin in serum, it plays a crucial role in type I hypersensitivity reactions, such as hay fever, asthma, hives, and anaphylactic shock. IgE is produced by terminally differentiated plasma B cells and basophils. It binds to Fc epsilon receptors on mast cells and basophils, leading to the release of histamine and other molecules that promote allergic responses. Crosslinking of IgE bound to these receptors induces degranulation of mast cells and basophils, resulting in allergic manifestations. In addition to its role in allergic responses, IgE is functionally important for immunity against parasites, highlighting its dual role in both protective and pathological immune processes.
