          Product Specific Information

          Description
          The MIH1 monoclonal antibody reacts with human B7-H1, also known as PD-L1. B7-H1, a member of the B7 family, has a predicted molecular weight of approximately 40 kDa and belongs to the Ig superfamily. B7-H1 is expressed on a majority of leukocytes. B7-H1 is a ligand for PD-1. Interaction of PD-1 with either PD-L1 (B7-H1) or PD-L2 (B7-DC) results in inhibition of T and B cell responses. MIH1 is reported to be a blocking antibody.

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

          Applications Tested
          This MIH1 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 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

          Programmed death receptor ligand 1 (PD-L1, also called B7-H1) is a recently described B7 family member. To date, one specific receptor has been identified that can be ligated by PD-L1. This receptor, programmed death receptor 1 (PD-1), has been shown to negatively regulate T-cell receptor (TCR) signaling. Upon ligating its receptor, PD-L1 has been reported to decrease TCR-mediated proliferation and cytokine production. PD-L1 expression was found to be abundant on many murine and human cancers and could be further up-regulated upon IFN-gamma stimulation. Thus, PD-L1 might play an important role in tumor immune evasion.
