Target

  • Function

    Implicated in tumor cell metastasis. May function in protection of the lysosomal membrane from autodigestion, maintenance of the acidic environment of the lysosome, adhesion when expressed on the cell surface (plasma membrane), and inter-and intracellular signal transduction. Protects cells from the toxic effects of methylating mutagens.
  • Tissue specificity

    Isoform LAMP-2A is highly expressed in placenta, lung and liver, less in kidney and pancreas, low in brain and skeletal muscle. Isoform LAMP-2B is highly expressed in skeletal muscle, less in brain, placenta, lung, kidney and pancreas, very low in liver.
  • Involvement in disease

    Defects in LAMP2 are the cause of Danon disease (DAND) [MIM:300257]; also known as glycogen storage disease type 2B (GSD2B). DAND is a lysosomal glycogen storage disease characterized by the clinical triad of cardiomyopathy, vacuolar myopathy and mental retardation. It is often associated with an accumulation of glycogen in muscle and lysosomes.
  • Sequence similarities

    Belongs to the LAMP family.
  • Post-translational
    modifications

    O- and N-glycosylated; some of the 16 N-linked glycans are polylactosaminoglycans.
  • Cellular localization

    Cell membrane. Endosome membrane. Lysosome membrane. This protein shuttles between lysosomes, endosomes, and the plasma membrane.

      Exposure time: 20 minutes


      This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system under denaturing, reducing conditions. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes.  After transfer, the membrane was blocked for an hour in 3% milk before being incubated overnight at 4°C with mouse monoclonal [H4B4] to LAMP2 (ab25631; diluted 1:5000).  Antibody binding was detected using peroxidase labelled goat anti-mouse IgG (ab97040; diluted 1:50000) for an hour at room temperature and visualised using ECL development solution.

      Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffers EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab25631, 0.5µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in THP1 cells fixed with methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

      Along with THP-1 macrophages, other human cell lines were loaded, and the 110 kDa mature band for LAMP2 was detected in all the samples. On the other hand, mouse and rat cells were negative. The antibody works really good on human samples, detecting a single 110 kDa band but it's not suitable to use for mouse or rat samples.

    Answer

    Vielen Dank für Ihre Anfrage die Herr Hryca uns in den technischen Dienst weitergeleitet hat.

    Ich habe geschaut, und wir haben viele möglichen positiven Kontrollen für Sie. Können Sie mir bitte noch sagen, welche Art von positive Kontrolle Sie benötigen? Ist es ein Lysat für Western blot oder ein Gewebeschnitt für Immunohistochemie? Haben Sie auch eine Präferenz für eine Spezies (Maus, human)?

    Hier mal eine Aufstellung von möglichen positiven Kontrollen. Ich freue mich wieder von Ihnen zu hören, um Ihnen genaure Vorschläge machen zu können.

    Answer

    Thank you for your reply.

    The antibodies differ in the immunogen, tested applications, tested species, purification, concentration, amount and price.

    Please see the datasheets for each antibody for this information.
    ab25631: https://www.abcam.com/lamp2-antibody-h4b4-lysosome-marker-ab25631.html
    ab119124: https://www.abcam.com/lamp2-antibody-h4b4-azide-free-ab119124.html
    ab112019: https://www.abcam.com/lamp2-antibody-h4b4-ab112019.html

    My recommendationwould be touse ab25631 for the IP testing as it has been used in many different applications as well. It has been referenced in publications as well as customers have submitted their feedback in form of Abreviews (https://www.abcam.com/LAMP2-antibody-H4B4-Lysosome-Marker-ab25631-reviews.html).

    I'd be happyto send you a testing discount code. Please let me know for which antibody you would like to receive the code.

    I look forwad to hear back from you.

    Thank you for contacting us.

    The clone was raised against human adherent peripheral blood cells. The epitope it recognizes is unmapped.

    Question

    ab25630: WB with rat liver
    sees band at 25 kDa
    transfer is OK, detects other proteins in the blot
    Ab: 1/1000 1-2 h RT
    block: overnight 4 degree
    secondary: OK
    antibody from other company to same protein gives same results
    suggestions: WB conditions might not yet be optimal, try blocking for only 1-2 h RT, antibody incubation: overnight 4 degree
    ab25631: rat is unsuitable
    ab2773: WB with rat liver, sees band at 25 kDa
    suggestions: WB conditions might not yet be optimal, try blocking for only 1-2 h RT, antibody incubation: overnight 4 degree

    Answer

    Thank you for contacting us.
    I am sorry to hear about the problems you have encountered.

    The bands you are seeing at 25 kDa could be the light chain of endogenous IgG.

    As we discussed over the phone, please try the following suggestions as it seems the WB conditions for these 2 antibodies (ab25630 and ab2773) are not yet optimal:

    1) try blocking for only 1-2 h RT
    2) try the primary antibody incubation for overnight 4 degree

    As for ab25631, this has been shown to not react with rat samples and would probably not give satisfactory results.However, if you have access to a human sample, you could try the antibody on that.

    Please let me know if the tips were helping to improve your results.

    I hope this information is helpful to you, and I look forward to hear back.

    Does antibody H4B4 recognize LAMP-2B?

    Asked on Aug 09 2011

    Answer

    Thank you for contacting us. In humans, the three splice variants (LAMP-2A, LAMP-2B and LAMP-2C) all have identical extracellular domains. It is also known that LAMP-2A is distributed rather ubiquitously, while LAMP-2B is expressed predominantly in striated muscle and brain. Clone H4B4 has been shown to stain for LAMP-2 in skeletal muscle. This information leads us to believe that this antibody will react with LAMP-2B, though we have not verified this through in-house testing. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
