HLA-A3 Antibody (H071T03B06-A) in Flow
Normal human peripheral blood cells were either left unstained (blue histogram) or stained with HLA-A3 Monoclonal Antibody, NovaFluor Blue 610-70S (purple histogram). Total viable cells in the lymphocyte gate 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 monoclonal antibody GAP.A3 reacts with the human major histocompatibility complex (MHC) class I molecule HLA-A3, which is a member of the HLA-A family. HLA-A3 is expressed by 15-25% of cancer patients and has been demonstrated to bind the tumor-associated antigen human telomerase reverse transcriptase (hTERT).
This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer.
Applications Tested
This GAP.A3 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.6 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
HLA-A3 is a subtype of the HLA class I heavy chain paralogues, existing in two forms: HLA-A3.1 and HLA-A3.2, which differ at amino acid positions 152 and 156. HLA class I molecules are heterodimers consisting of a heavy chain and a light chain (beta-2 microglobulin), with the heavy chain anchored in the membrane. These molecules are highly polymorphic cell surface glycoproteins expressed on nearly all nucleated cells. HLA class I molecules play a central role in the immune system by presenting intracellular peptides derived from the endoplasmic reticulum lumen on the cell surface. Non-native peptides are recognized by circulating cytotoxic T lymphocytes, facilitating immune surveillance. The heavy chain of HLA-A is approximately 45 kDa and its gene contains 8 exons. Exons 2 and 3 encode the alpha1 and alpha2 domains, which bind the peptide, while exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region, and exons 6 and 7 encode the cytoplasmic tail. Polymorphisms within exons 2 and 3 determine the peptide binding specificity of each class I molecule, and typing for these polymorphisms is routinely performed for bone marrow and kidney transplantation. Hundreds of HLA-A alleles have been described, and HLA and MHC antibodies are crucial in immunopeptidomics, aiding in the identification and characterization of neoantigens through techniques such as high-performance liquid chromatography coupled to tandem mass spectrometry.
