  • 描述
    小鼠单克隆抗体[B2M-01] to beta 2 Microglobulin
  • 宿主
    Mouse
  • 特异性
    This antibody reacts with beta-2-microglobulin, associated with cell-surface MHC Class I molecules and other membrane antigens as well as with soluble forms of beta-2-microglobulin. The antibody detected beta-2-microglobulin in U-937 and RAJI cell lines in WB in non reducing conditions however failed to detect a band in JEG-3 and A431 cell lysates. All lysates gave a signal in direct ELISA.

应用

Our Abpromise guarantee covers the use of ab759 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ELISA Use at an assay dependent concentration.
Flow Cyt Use at an assay dependent concentration.

ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
IP Use at an assay dependent concentration.
RIA Use at an assay dependent concentration. Dissociation constant of the antibody-soluble b2-microglobulin is 1.5 x 10-8 mol/l as determined by competitive RIA.
WB Use a concentration of 2 µg/ml. Use under non reducing condition. Detects a band of approximately 13 kDa (predicted molecular weight: 13 kDa). Use under non reducing conditions. Incubate overnight. Block with 5%milk for 2hrs.

靶标

  • 功能
    Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
  • 疾病相关
    Defects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:241600]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.
    Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states. The capacity to assemble into amyloid fibrils is concentration dependent. Persistently high beta(2)-microglobulin serum levels lead to amyloidosis in patients on long-term hemodialysis.
  • 序列相似性
    Belongs to the beta-2-microglobulin family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
  • 翻译后修饰
    Glycation of Ile-21 is observed in long-term hemodialysis patients.
  • 细胞定位
    Secreted. Detected in serum and urine.

      Developed using the ECL technique.

      Performed under non-reducing conditions.

      Predicted band size: 13 kDa



      Lysates were separated on 15% SDS–PAGE gel and electrotransferred to a PVDF membrane. The membrane was blocked in PBS/Tween buffer containing 5% non fat dry milk for 2 hours and probed with ab759 at 4°C overnight.

    Question

    I am not seeing any band in human endothelial cells. I load 30 ug, tried denatured, reducing conditions, incubated primary overnight at 4 degrees, tried 1/500-1/1000. Do I need to use non-reduced, non-denaturing conditions? Can you send me a picture of the blot you did?

    Answer

    Thank you for contacting us for technical support regarding ab759. I have contacted the laboratory and was able to find out that indeed non reducing conditions are advised with this antibody. I have added immediately on our datasheet (accessible below) this information and the image of the blot where four lysates were tested and where you can see a clear band of beta 2 Microglobulin with two lysates (U-937 cell lysate and Raji cell lysate). We expected a signal on Jeg3 cells since on the native lysate it worked by ELISA (ab759 as detecting antibody, directly conjugated with HRP). However, for WB condition, the lysate was not reduced (only denatured by SDS), which may explain the lack of signal with this lysate (furthermore each lysate preparation was not done at the same time). Therefore collectively, the antibody works in western blotting in non reduced conditions and you may find you can achieve a signal with non reducing conditions. May I also suggest to use a 15 or 20% gel to achieve a good separation and run a positive control of U-937 cell lysate or Raji cell lysate? We used a concentration of 2ug/ml of ab729, incubating overnight and blocking for 2hrs with 5% non fat milk. I hope this information will help you, please do not hesitate to contact me again if I can be of further assistance,

    Question

    I have a customer who urgently needs and anti-beta 2 Microglobulin antibody (for use in Western Blotting). I have been told by many of our suppliers that this clone (B2M-01) has died; and that the product will be on indefinate back order. Have you had any problems with this antibody (AB759)? If not, could you tell me what the availability of it would be? Thanking you in advance for your time and consideration in this matter, I will look forward to your response.
