Rabbit IgG Fc fragment

Code CSB-NP005201Rb
Product Type Native Protein
Size US$2000
Relevance The fragment crystallizable region (Fc region) is the tail region of an antibody that interacts with cell surface receptors called Fc receptors and some proteins of the complement system. This property allows antibodies to activate the immune system. InIgG, IgA and IgD antibody isotypes, the Fc region is composed of two identical protein fragments, derived from the second and third constant domains of the antibody's two heavy chains; IgM and IgE Fc regions contain three heavy chain constant domains (CH domains 2–4) in each polypeptide chain. The Fc regions of IgGs bear a highly conserved N-glycosylation site. Glycosylation of the Fc fragment is essential for Fc receptor-mediated activity. The N-glycans attached to this site are predominantly core-fucosylated diantennary structures of the complex type. In addition, small amounts of these N-glycans also bear bisecting GlcNAc and α-2, 6 linked sialic acid residues. The other part of an antibody, called the Fab region, contains variable sections that define the specific target that the antibody can bind. By contrast, the Fc region of all antibodies in a class are the same for each species; they are constant rather than variable. The Fc region is, therefore, sometimes incorrectly termed the "fragment constant region".

Q&A
Q:

Hello, I would like to inquire about CSB-NP005801m and CSB-NP005201Rb. Are they all digested with papain? Do you have human IgG?

A:

For CSB-NP005801m and CSB-NP005201Rb, these two natural proteins were catalyzed by papain.
Yes, we supply Human IgG Fc fragment . The product code is CSB-NP005401h.
