Overview

  • Product name
    Anti-beta 2 Microglobulin antibody [B2M-01] (Phycoerythrin)
    See all beta 2 Microglobulin primary antibodies
  • Description
    Mouse monoclonal [B2M-01] to beta 2 Microglobulin (Phycoerythrin)
  • Host species
    Mouse
  • Conjugation
    Phycoerythrin. Ex: 488nm, Em: 575nm
  • Specificity
    This antibody reacts with beta 2 microglobulin (b2M) associated with cell-surface MHC Class I molecules and other membrane antigens as well as with soluble beta 2 microglobulin. Beta 2 mircoglobulin is a 12 kDa Ig like glycoprotein expressed on lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells and epithelial cells. It is absent on erythrocytes.

Target

  • Function
    Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
  • Involvement in disease
    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.
  • Sequence similarities
    Belongs to the beta-2-microglobulin family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
  • Post-translational
    modifications
    Glycation of Ile-21 is observed in long-term hemodialysis patients.
  • Cellular localization
    Secreted. Detected in serum and urine.

Customer reviews and Q&As

Answer

Vielen Dank für die Anfrage. Dass ab46793 nicht auf der Liste auftaucht, bedeutet dass er nicht getestet wurde, ob er mit Maus kreuzreagiert. In der Tat ist ab46793 für die Immunhistochemie (IHC-P/Fr - neben anderen Anwendungen wie Durchflusszytometrie) garantiert. Allerdings ist dieser CD44- Antikörper mit dem Tandemkonjugat PE-Cy7 gekoppelt. Welche Anregungswellenlängen beziehungsweise Filter Du für die Detektion benötigst, kannst Du anhand des Spektrums ersehen (Details dazu in Spectra-Viewern von eBioscience http://www.ebioscience.com/resources/fluorplan-spectra-viewer.htm  oder Biolegend http://www.biolegend.com/spectraanalyzer etc.) und beim Hersteller des Mikroskops erfragen. Im Allgemeinen sind PE und Tandem-Fluorochrome wie PE-Cy7 jedoch recht instabil und besitzen eine schwache Fluoreszenz-Intensität, so dass sie in der Regel wenig für die Mikroskopie geeignet sind. Wie auf dem Datenblatt von ab46793 beschrieben, würde ich deswegen für die Detektion dieses CD44- Antikörpers in der IHC einen sekundären Antikörper wie zum Beispiel ab96879 oder ab98697 empfehlen (je nach Fluorochrom-Belegung bei einer Mehrfachfärbung beziehungsweise vorhandenem Filtersystem). Daher ist es eigentlich nicht notwendig, den Klon [F10-44-2] als PE-Cy7-Konjugat zu nehmen (es sei denn, es sind noch andere Experimente damit geplant), sondern Du kannst ihn auch unkonjugiert erwerben (ab6124): ab6124: Click here (or use the following: https://www.abcam.com/index.html?datasheet=6124). ab96879: Click here (or use the following: https://www.abcam.com/index.html?datasheet=96879). ab98697: Click here (or use the following: https://www.abcam.com/index.html?datasheet=98697).
