IgM Antibody (M018T02Y03-A) in Flow

BALB/c mouse bone marrow cells were unstained (left) or stained with 1 µg of IgM Monoclonal Antibody, NovaFluor Yellow 610 (right). All cells were co-stained with CD45R (RA3-6B2) Monoclonal Antibody, eFluor 450 (Product # 48-0452-82). Total viable cells were used for analysis, as determined by LIVE/DEAD Blue (Product # L34962). Data was acquired on a 5-laser Cytek Aurora and unmixed with autofluorescence extraction.

Product Specific Information

Description
The II/41 monoclonal antibody reacts with the mu heavy chain of mouse IgM. It does not react with other classes of mouse immunoglobulin including IgD, IgG or IgA. IgM is expressed intracellularly, during early stages of B lymphopoiesis, and then on the surface of more mature B cells in the bone marrow and peripheral B cells. Fluorochrome conjugated II/41 can be used as a detection secondary for mouse IgM.

This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer.

Applications Tested
This II/41 antibody has been tested by flow cytometric analysis of mouse bone marrow cells. This can be used at less than or equal to 1.0 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. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

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

Our internal testing shows that NovaFluor Yellow 610 non-specifically stains B cells in SJL mice. Non-specific staining has not been observed in BALB/c or C57BL/6 mice. Other strains have not been tested. See the Antibody Testing Data for an example of this strain-dependent difference.

Target Information

Mouse IgM is an immunoglobulin M antibody that is produced by B cells in response to an antigen. It is the first antibody produced during an immune response and is the largest immunoglobulin in the serum. Mouse IgM is composed of five heavy chains and five light chains, and it is involved in complement activation and agglutination of antigens. It plays a crucial role in the innate immune response and is important for neutralizing pathogens before the adaptive immune response is fully activated. Mouse IgM is widely used in research and diagnostic applications, including ELISA, Western blotting, and immunohistochemistry.
