Description
The A2MR-a2 monoclonal antibody reacts with human CD91, also known as LRP-1 and alpha-2 macroglobulin receptor.
This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer.
Applications Tested
This A2MR-a2 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.05 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

CD91 is a 600 kDa type I transmembrane protein composed of an alpha and beta chain. The alpha chain interacts with a variety of structurally and functionally diverse ligands, while the beta chain contains two tyrosine phosphorylation motifs that interact with adaptor and signaling proteins. This receptor is expressed by cells in the monocytic lineage, dendritic cells, hepatocytes, fibroblasts, adipocytes, neurons, and syncytiotrophoblasts. CD91 plays a crucial role in several cellular processes, including ligand endocytosis and trafficking to lysosomes, intracellular signaling, lipid homeostasis, and clearance of apoptotic cells. It is involved in cross-presenting antigens via MHC class I molecules on antigen-presenting cells after endocytosis of heat shock protein-peptide complexes. Additionally, CD91 is essential for the A2M-mediated clearance of secreted amyloid precursor protein and beta-amyloid, the main component of amyloid plaques found in Alzheimer patients. Expression of CD91 decreases with age and is found to be lower in brain tissue from Alzheimer patients compared to controls. The receptor also plays a role in cell migration and activating signaling cascades, highlighting its importance in both immune function and disease processes.
