Description

Rabbit Recombinant Monoclonal Antibody

This product is preservative free. It is recommended to add sodium azide to avoid contamination (final concentration 0.05%-0.1%). Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire. This antibody has specificity for Mouse CD55/DAF.

CD55 (decay-accelerating factor, DAF) is a GPI-anchored membrane glycoprotein that protects autologous cells from classical and alternative pathway of complement cascade. Bidirectional interactions between CD55 and CD97 are involved in T cell regulation and CD55 can regulate complement when bound to CD97. In tumors, CD55 promotes neoangiogenesis, tumorigenesis, invasiveness and evasion of apoptosis. CD55 is a 70 kDa glycoprotein (in erythrocytes) anchored in the membrane by glycosylphosphatidylinositol tail. In other cells, the apparent molecular weight is somewhat larger for CD55 and has a substantial content of O-glycans. CD55 binds to activated C4b or C3b complement fragments on the cell surface, preventing the assembly and accelerating the decay of both classical and alternative pathways. CD55 carries the Cromer related blood group antigens. Two alternatively spliced transcripts encoding CD55 have been identified, and the predominant transcript encodes a membrane-bound protein expressed on cells exposed to plasma component proteins but an alternatively spliced transcript produces a soluble protein present at much lower levels. CD55 has been studied to have a role in prostate cancer growth and survival.

Frequently Asked Questions (FAQs)

Have you tested the CD55 Monoclonal Antibody (583905) (Cat. No. MA5-24264) in ICC/IF application?

Unfortunately, this antibody has not been internally verified for ICC/IF, and therefore we cannot guarantee that it will work for this application.

Alternatively, we offer CD55 Recombinant Rabbit Monoclonal Antibody (76) (Cat. No. MA5-29678) and CD55 Polyclonal Antibody (Cat. No. PA5-88462) that target mouse and have been verified for ICC/IF.
