  • Western blot detection of human secretory phospholipase A2 (25µg)

    ab23705 at 1/1000 western blot detection of 0.25 ug of human secretory phospolipase A2.
  • IHC image of ab23705 staining in human pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab23705, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Vielen Dank für Ihren Anruf.

Das Labor, das Anti-Phospholipase A2Antikoerper ab23705 herstellt, hat bestätigt, dass das Immunogen das Volllängenprotein sPLA2 (human Type IIA) mit der SwissProtID P14555.2 ist. Damit ist dieser Antikörper spezifisch für die Membran-assoziierte PLA2.

Die Antikörper ab124230 und ab73406 sind hingegen spezifisch für die cytosolische PLA2 mit der SwissProtID P47712.

Da diese beiden Formen sehr unterschiedlich sind, haben wir leider keinen Antikörper verfügbar, der beide Formen erkennt.

Ich hoffe, diese Informationen helfen Ihnen weiter. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

Thank you for contacting Abcam.

Under our Abpromise we guarantee our products to work as stated on the datasheet and if they do not work as stated, and we cannot resolve the issue you are having with the antibody then we would be happy to either send a replacement antibody or to process a refund.

In the case of ab23705, we guarantee to work in IHC-P, WB, IP on rat and human tissue. On the webpage for this product we have a Abreview and a publication that have used the antibody successfully in IHC-P in pancreatic tissue. However we have not tested it on brain sections.

Please let me know if there is anything else I can help you with.

Hi. I am inquiring about the sPLA2 rabbit poly-clonal antibody and its use in IHC-P. I have attempted numerous studies on human brain tissues using sPLA2 antibodies from other vendors and have not had consistent results and am considering trying AbCam. There is one published article from China in which they uses the antibody on rats pancreas but did not give details on which antigen retrieval buffer they used nor the source of their secondary antibody. Additionally, they incubated at 37C for all three steps. Your data information sheet is from formalin-fixed human tissue, using citrate buffer for AR, a short primary antibody incubation step at room temperature, but the secondary/tertiary reagents are not typical of what I have available. I will be using a manual LSAB system (we are a laboratory with somewhat limited funds at the moment), Tris/Tween buffer wash (I noticed that your standard protocol calls for Triton X) with DAB as the chromagen. I have read your information on IHC protocols but not sure what the data sheet for ab23705 is referring to for "protocol F". Do you think I will have success with your antibody or will I need to move up to a more sensitive detection system? There is not a lot of published results for sPLA2 IHC on human formalin-fixed tissues for me to ascertain whether my normal IHC protocol will be successful. I usually go overnight with the primary antibody at either 4C or room temperature. I would appreciate additional information on the HRP conjugated compact polymer system that you utilized in your studies for development of the antibody. Thanks much for any suggestions that you may have as I try to convince my PIs that we need to consider a new source for the sPLA2 antibody.

Thank you for contacting us. This product should work well with your conditions but of course must be optimized by the customer. This product was tested with short incubation time but may be used overnight at 4 degrees if you find you need a stronger signal. We do guarantee our products to work in our tested spcies and applications and will be happy to troubleshoot any product you are not having success with. We also can provide a free of charge replacement, credit, or refund within 6 months of purchase if the product is not working well. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
