Application Notes: Flow Cytometry: 10 μg/mL (final concentration). ELISA: 1 μg/mL (for capture antibody). Not recommended for Western blot and Immunoprecipitation.

Protocol: Flow Cytometric analysis for floating cells We usually use Fisher tubes or equivalents as reaction tubes for all steps described below. 1) Wash the cells 3 times with washing buffer [PBS containing 2 % fetal calf serum (FCS) and 0.1 % NaN3]. 2) Resuspend the cells with washing buffer (5 x 10e6 cells/mL). 3) Add 50 μL of the cell suspension into each tube, and centrifuge at 500 x g for 1 minute at room temperature (20~25 °C). Remove supernatant by careful aspiration. 4) Add 20 μL of Clear Back (human Fc receptor blocking reagent) to the cell pellet after tapping. Mix well and incubate for 5 minutes at room temperature. 5) Add 40 μL of the primary antibody at the concentration as suggest in the APPLICATIONS diluted in the washing buffer. Mix well and incubate for 30 minutes at room temperature. 6) Add 1 mL of the washing buffer followed by centrifugation at 500 x g for 1 minute at room temperature. Remove supernatant by careful aspiration. 7) Add 30 μL of 1:100 FITC conjugated anti-mouse IgG diluted with the washing buffer. Mix well and incubate for 15 minut es at room temperature. 8) Add 1 mL of the washing buffer followed by centrifugation at 500 x g for 1 minute at room temperature. Remove supernatant by careful aspiration. 9) Resuspend the cells with 500 μL of the washing buffer and analyze by a flow cytometer. (Positive controls for Flow cytometry 293T, Jurkat) ELISA 1) Distribute 100 μ L/well of the anti-MICB monoclonal antibody (BMO1) (1 μg/mL) diluted with PBS to each well. 2) Incubate it overnight at 4 °C. 3) Add 100 μ L/well of 15 % BSA/PBS. 4) Incubate it for 1 hour at 37 °C. 5) Wash the plates 4 times with PBS-T [0.05 % Tween-20 in PBS]. 6) Distribute 100 μL/well of the samples or the recombinant MICB standard (0~20 ng/mL) diluted with 7.5 % BSA/PBS to each well. 7) Incubate it for 2 hours at 37 °C. 8) Wash the plates 4 times with PBS-T. 9) Distribute 100 μL/well of the anti-MICA/B monoclonal antibody (BAMO3) (1 μg/mL) diluted with 7.5 % BSA/PBS to each well. 10) Incubate it for 2 hours at 37 °C. 11) Wash the plates 4 times with PBS-T. 12) Distribute 100 μL/well of the 1:2,000 HRP-conjugated anti-mouse IgG2a diluted with 3.75 % BSA/PBS to each well. 13) Incubate it for 1 hour at 37 °C. 14) Wash the plates 6 times with PBS-T. 15) Distribute 100 μL/well of the tetra-methylbenzidine (TMB) containing solution. 16) Incubate it for 5~60 minutes. The condition for reaction may vary. 17) Distribute 100 μL/well of 1 M H2SO4 to each well and stop enzyme reaction. 18) After gentle mixing, determine the absorbance at 450 nm of each well by a spectrophotometer.

Target Details for MICB

Target: MICB (MHC Class I Polypeptide-Related Sequence B (MICB))

Alternative Name: mic-b

Background: MICA and MICB (Major Histocompatibility Complex class I Chain-related gene A and gene B) bind to the activating immunoreceptor NKG2D. NKG2D is expressed on NK (Natural Killer) cells, NKT cells, i i T cells and CD8+i !i T cells. Recognition of MICA and MICB by NKG2D is involved in tumor surveillance, immune responses to viral infections and autoimmune diseases. MICA and MICB are transmembrane glycoproteins that are distantly related to the MIC proteins, and they possess three extra-cellular Ig-like domains. And thus, MICA and MICB are closely related but are functionally indistinguishable. MICA and MICB molecules are highly glycosylated, and are detected as a smear band ranging from 65-75 kDa. It is reported that MICA and MICB are highly expressed in variant tumor cells, whereas normal cells express little. Tumor cells have been shown to shed and release MIC molecules from the cell surface. Therefore determination of soluble MIC (sMIC) levels provides valuable information for cancer staging, and sMIC in serum seems to be an indicator for systemic manifestation of malignancy rather than for local tumor extent.
