  • Relevance
    Blood-group antigens are generally defined as molecules formed by sequential addition of saccharides to the carbohydrate side chains of lipids and proteins detected on erythrocytes and certain epithelial cells. The A, B and H antigens are reported to undergo modulation during malignant cellular transformation. Blood group related antigens represent a group of carbohydrate determinants carried on both glycolipids and glycoproteins. They are usually mucin-type, and are detected on erythrocytes, certain epithelial cells, and in secretions of certain individuals. Sixteen genetically and biosynthetically distinct but inter-related specificities belong to this group of antigens, including A, B, H, Lewis A, Lewis B, Lewis X, Lewis Y, and precursor type 1 chain antigens.

Thank you for contacting us.

I have received the following information:

ab2521: the IHC(P) application was tested on human colon carcinoma tissue. The paraffin-embedded sections were deparaffinized by xylene, hydrated by 100%, 90%, 75% ethanol and distilled water, incubated with 5% H2O2, blocked with porcine serum devoid of ABO-reactive antibodies and then incubated with primary antibody, secondary antibody, and the signal was developed by DAB.

ab3354: This products has been tested on FFPE normal human kidney tissue. We recommend using a 20min incubation of the primary @ 1:40 dilution and no antigen retrieval should be needed.
I am inquiring about more specificity-testing information with the lab.

ab24222: Unfortunately, the antibodywas not tested for WB, just in ELISA type format. Here, I am also inquiring about more specificity-testing information with the supplying lab for ELISA. I have updated our datasheet and removed WB. I am sorry for the incorrect information.

I will be in touch with more details, buthope this information is already of some help to you.

Please do not hesitate to contact us if you need any more advice or information.
