Background of Siglec-2/CD22

CD22 is a surface glycoprotein of B lymphocytes that is rapidly phosphorylated on cytoplasmic tyrosines after antigen receptor cross-linking. It is a negative regulator of antigen receptor signaling whose onset of expression at the mature B cell stage may serve to raise the antigen concentration threshold required for B cell triggering. The human CD22 gene is expressed specifically in B lymphocytes and likely has an important function in cell-cell interactions. The B cell coreceptor CD22 plays an important role in regulating signal transduction via the B cell Ag receptor. And CD22 is located within the band region q13.1 of chromosome 19.

Question

We are currently using anti-CD22 antibody PB9691 for rat tissue, and we are satisfied with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on pig tissues as well?

Verified Customer

Verified customer

Asked: 2020-01-30

Answer

The anti-CD22 antibody (PB9691) has not been validated for cross reactivity specifically with pig tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in pig you can get your next antibody for free. Please contact me if I can help you with anything.

Question

Our lab were content with the WB result of your anti-CD22 antibody. However we have observed positive staining in tonsil cell membrane using this antibody. Is that expected? Could you tell me where is CD22 supposed to be expressed?

Verified Customer

Verified customer

Asked: 2019-11-11

Answer

From what I have seen in literature, tonsil does express CD22. Generally CD22 expresses in cell membrane. Regarding which tissues have CD22 expression, here are a few articles citing expression in various tissues:
Spleen, Pubmed ID: 15057824
Tonsil, Pubmed ID: 1985119

Question

We ordered your anti-CD22 antibody for WB on tonsil last year. I am using human, and We intend to use the antibody for IHC-P next. I am interested in examining tonsil as well as corpus callosum in our next experiment. Could you please give me some suggestion on which antibody would work the best for IHC-P?

Verified Customer

Asked: 2018-12-18

Answer

I viewed the website and datasheets of our anti-CD22 antibody and it seems that PB9691 has been tested on human in both WB and IHC-P. Thus PB9691 should work for your application. Our Boster satisfaction guarantee will cover this product for IHC-P in human even if the specific tissue type has not been validated. We do have a comprehensive range of products for IHC-P detection and you can check out our website bosterbio.com to find out more information about them.
