    Spezifität
    This antiserum is directed against human NOTCH 2. Based on sequences, we expect this antibody to react as well with rat and mouse NOTCH 2. Only one amino acid difference (conservative) occurs in mouse and rat. The immunogen epitope is only exposed after gamma secretase cleavage and is not accessible in the uncleaved form.
    Produktmerkmale
    Anti Notch 2 Antibody recognizes Notch 2 that is synthesized in the endoplasmic reticulum as an inactive form which is proteolytically cleaved by a furin-like convertase (S1 cleavage) in the trans-golgi network before it reaches the plasma membrane to yield an active, ligand-accessible form. Cleavage results in a C-terminal fragment N(TM) and a N-terminal fragment N(EC). Following ligand binding, it is cleaved (S2 cleavage) by TNF-alpha converting enzyme (TACE) to yield a membrane-associated intermediate fragment called Notch extracellular truncation (NEXT). This fragment is then cleaved by presenilin-dependent gamma-secretase (S3 cleavage) to release the intracellular domain (NICD) from the membrane.

    Immunogen
    This whole rabbit serum was prepared by repeated immunizations with a synthetic peptide corresponding to amino acid residues of human Notch 2 located near the N-terminal sequence of the cleaved N intracellular domain (NICD).
    Immunogen Type: Peptide

    A strong response was detected by ELISA against the immunizing peptide.This product was assayed against the peptide immunogen in a standard capture ELISA using Peroxidase conjugated anti-Rabbit IgG [H&L] Goat) and ABTS (2,2’-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) as a substrate for 30 minutes at room temperature. A working dilution of 1:30,000 to 1:90,000 is suggested for this product.

    ABIN1043688 reveals two protein bands of the expected size and some weaker extraneous bands in cell lysates of human pluripotent stem cells, definite endoderm cells, pancreatic endoderm cells, and pancreatic progenitor cells.

    Full Protocol
    • Grow HUES8 in mTeSR1 (STEMCELL Technologies, 85850) at 37°C and 5% O2, 5% CO2 in 2ml in a 6-well plate to 90% confluency.
    • Harvest cells using TrypLE (ThermoFisher Scientific, 12604013) following the manufacturer´s instructions.
    • Lyse 2x106 cells in 30µl per well cold RIPA buffer (50mM Tris-HCl pH 8.0, 150mM NaCl, 0.1% SDS, 0.5% deoxycholate, 1% TritonX 100 in ddH2O) supplemented with 1mM PMSF and 1x protease inhibitor (Roche, 11836170001) for 30min on ice with 3x vortexing in 1.5ml microcentrifuge tubes.
    • Centrifuge tubes at 10000xg for 8min at 4°C.
    • Transfer supernatant to a new 1.5ml microcentrifuge tube and store at -80°C.
    • Determine total protein content of the lysates using a Bradford assay (Bio-Rad, 500-0006).
    • Denature 50µg of total protein for 5min at 95°C in 30µl 1x Laemmli SDS sample buffer and subsequently separate them on a denaturing 7.5% polyacrylamide gel (7.5% Acrylamide, 0.375M Tris-HCl pH8.8, 0.1% SDS, 0.1% APS, 0.1% TEMED) for about 120min at 120V.
    • Transfer proteins onto a PVDF membrane (Sigma Aldrich, IPVH00010) with transfer buffer (5.27g Tris, 2.93 g glycerine, 200 ml methanol, fill to 1l ddH2O) in a semidry western blotting system for 80min at 80mA/gel.
    • Check transfer of the separated proteins by Ponceau S staining.
    • Rinse membrane with water.
    • Wash membrane for 5min with TBST (TBS, 0.02% Tween20).
    • Block the membrane with 20ml blocking buffer (TBST, 5% milk) on a shaker for 1h at RT.
    • Rinse membrane 3x with TBST.
    • Wash membrane on a shaker 3x for 5min with TBST.

      • rabbit anti-NOTCH2 antibody (antibodies-online, ABIN1043688) diluted 1:1000 respectively in blocking buffer ON at 4°C or
      • mouse anti-vinculin antibody (SigmaAldrich, V9264) diluted 1:1000 in blocking buffer at RT for 1h.
    • Wash membrane 3x for 5min with TBST.
    • Incubate membrane with secondary
      • donkey anti-rabbit HRP-conjugated antibody (GE Healthcare, NA9310V) diluted 1:5000 in TBST containing 1% milk for 1h at RT or
      • donkey anti-mouse HRP-conjugated antibody (GE Healthcare, NA9340V) diluted 1:5000 in TBST containing 1% milk for 1h at RT.
    • Wash membrane 3x for 5min with TBST.
    • Reveal protein bands using ECL solution (ThermoScientific, 34076) with an exposure time of 40min for the ABIN1043688 and 2min for the vinculin loading control.
    Anmerkungen
    • ABIN1043688 revealed some strong unspecific bands. Nevertheless, a band over 250kDa appears to be highly specific, as it is only detected at day 10 (lanes 5 and 6) and day 14 (lanes 7 and 8).

    • Manual exposure had to be performed due to a defect of the fusion detector in our institute.

    • ABIN1043688 was also tested in IHC on 4-5µm FFPE sections of primary human kidney cancer tissue. Epitope retrieval was carried out using Tris-EDTA buffer at pH9.0 (Zytomed, ZUC029-500), EDTA at pH8.0 (Leica, RE7116), or citrate buffer at pH6.1 (Agilent, S169984-2) for 20min in a decloaking chamber.

    • Interpretation of the results was difficult, as the method of antigen retrieval strongly effects the staining pattern. Antigen retrieval using the citrate buffer at pH6 might be ok, but knockout or knockdown studies are necessary to clearly conclusively show specificity.
