  • Relevance

    Pancreatic amylase is a digestive enzyme secreted by the pancreas. It consists of a single polypeptide chain with a molecular weight of 54 kDa. Pancreatic amylase occurs in serum at a concentration of about 60µg/L, from a total amylase concentration in serum of about 120µg/L. Pancreatic amylase and salivary amylase are the products of separate genes and, although they share 98% amino acid sequence homology, they differ in molecular size, isoelectric point and antigenic properties. Measurement of amylase concentrations in serum is a diagnostic test for various pancreatic disorders (especially acute and relapsing pancreatitis).

  • IHC image of Pancreatic Amylase staining in Human pancreas normal 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 ab21156, 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.

  • ab21156 staining Pancreatic alpha amylase in mouse pancreas tissue in immunohistochemical analysis (Frozen sections).

    Tissue was blocked with 5% BSA for 30 minutes at 21°C. Samples were incubated with primary antibody for 1 hour at 21°C at 1/800 dilution. Renaissance background reducing diluent was used. An Alexa Fluor488-conjugated goat anti-rabbit IgG monoclonal (H+L) was used as secondary antibody at 1/200 dilution.

Thank you for your inquiry.

Unfortunately, I am unable to issue discount code for the following antibodies:

ab60720, ab86704 and ab65109.

The immunogens for the MUC antibodies do not show a high enough homology (70% and below)to mouse to expect any cross-reactivity. Unfortunately, this is also true for the other antibodies we offer against these targets too.

ab86704 is already tested and guaranteed for mouse and WB. Please reassure your customer that the Abpromise guarantee will apply to this antibody in their experiment.


ab68715: xxxxx

ab86177: xxxxx

ab21156: xxxxx

Expiration date:17. May 2012

I am very pleased to hear your customer would like to accept our offer and test ab68715 and ab86177 and ab21156 in mouse.

The codes will give your customer 1 freeprimary antibody eachbefore the expiration date.

To redeem this offer, please submit an Abreview eachformouse and include this code in the “Additional Comments” section so we know the Abreview is for this promotion. Remember, we publish both positive and negative Abreviews on our datasheets so please submit the results of your tests.

Thank you for contacting us. Generally we predict reactivity of an antibody if the immunogen sequence has 85% or greater homology with the species being tested. The immunogen for ab35414 and ab82890 is full length pig protein and for ab21156 it is full length human protein, but BLAST search results showed both of these beneath the 85% reactivity mark. We haven't tested ab35414 or ab21156 in ICC and have no data on whether they work in this application. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
