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. CD22 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.3 CD22 is located within the band region q13.1 of chromosome 19.

Antibody Validation

Question

Can you help my question with product PA1018-1, anti-CD22 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

Verified Customer

Verified customer

Asked: 2019-10-11

Answer

It is not recommended storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PA1018-1 anti-CD22 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Question

Will PA1018-1 anti-CD22 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2019-03-19

Answer

You can see on the product datasheet, PA1018-1 anti-CD22 antibody as been validated on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

Question

Will anti-CD22 antibody PA1018-1 work on canine WB with tonsil?

K. Miller

Verified customer

Asked: 2017-03-28

Answer

Our lab technicians have not validated anti-CD22 antibody PA1018-1 on canine. You can run a BLAST between canine and the immunogen sequence of anti-CD22 antibody PA1018-1 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated canine samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in canine tonsil in WB, you can get your next antibody for free.
