Protein A/G MagBeads
$131.96 Add to cart View Product DetailsGenScript Protein A/G MagBeads are superparamagnetic beads covalently bound with recombinant proteins A and G for antibody purification. The beads are supplied as 25% slurry in phosphate buffered saline (PBS), pH 7.4, containing 20% ethanol. The Protein A/G MagBeads have a binding capacity of more than 10 mg Goat IgG per 1 ml settled beads.
Protein A/G is a genetically engineered protein (MW ≈43 kDa) that combines the IgG binding sites of both Protein A and Protein G. 6×His-tag was attached to its N-terminal to facilitate the purification. The secreted Protein A/G contains four Fc-binding domains from Protein A and two from Protein G, making it a more universal tool to bind and purify immunoglobulins.Product Details

GenScript Protein A/G MagBeads MX are ideal for small‐scale purification of antibodies
from plasma, serum, ascites, and cell

The
Protein A/G is a genetically engineered protein (MW≈43 kDa) that combines the
IgG binding sites of both Protein A and Protein G. It contains four Fc‐binding
domains from Protein A and two from Protein G, making it a universal tool to
bind and purify immunoglobulins (IgGs). GenScript’s Protein A/G MagBeads MX have
Protein A/G pre-coupled on the surface of superparamagnetic beads. To purify
antibodies, a sample containing the antibody of interest is incubated with the Protein
A/G MagBeads MX. The antibody binds to the Protein A/G on the beads during a
short incubation. This is followed by washing the beads to remove
non-specifically bound materials, and eluting the purified antibody. Magnetic
separation simplify purification process by eliminating the need for
centrifugation, minimizes sample loss and removes the excessive steps of a traditional
centrifugation-based purification method. -

Protein G
$90.56 Add to cart View Product DetailsProtein G, a cell surface protein of group G streptococci, is a Type III Fc receptor that binds to the Fc region of IgG by a non-immune mechanism similar to that of protein A from Staphylococcus aureus. This product contains three IgG binding domains, but its albumin-binding region has been removed. Additionally, His-tag and cysteine have been added to N- and C-termini, respectively, to facilitate purification and conjugation. This does not affect the protein’s ability to bind to IgG.

Protein G (recombinant)
$122.48 Add to cart View Product DetailsProtein G is a monomeric protein lacking cysteine residues. Recombinant Protein G is a highly stable surface receptor that is capable of binding the Fc portion of immunoglobulins, especially IgGs from a large number of species. Preparation:Protein G is from Streptococcus sp.expressed in E. coli.

Protein G, a bacterial cell wall protein isolated from group G Streptococci, binds to mammalian IgGs mainly through Fc regions. Native Protein G has three IgG binding domains and also the sites for albumin and cell-surface binding. Albumin and cell-surface binding domains have been eliminated from recombinant Protein G to reduce nonspecific binding. Protein G has greater affinity than Protein A for most mammalian IgGs, especially for certain subclasses including human IgG3, mouse IgG1 and rat IgG2a.

Protein G Resin
$111.26 Add to cart View Product DetailsDescription:
GenScript Protein G Resin is an affinity chromatography medium designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and cell culture media. The recombinant protein G ligand is coupled to 4% highly cross-linked agarose. The static binding capacity of Protein G Resin is over 20 mg sheep IgG/ml settled resin. The dynamic binding capacity will vary depending on several factors such as target antibody, flow rate etc.
Protein G, a bacterial cell wall protein isolated from group G Streptococci, binds to mammalian IgGs mainly through Fc regions. Native protein G has 3 IgG binding domains and also sites for albumin and cell-surface binding. The latter have been eliminated from recombinant protein G to reduce nonspecific binding. Although protein G has very similar tertiary structures to protein A, their amino acid compositions differ significantly, resulting in different binding characteristics. Protein G can be used for purification of mammalian monoclonal and polyclonal IgGs that do not bind well to protein A. Protein G has greater affinity than protein A for most mammalian IgGs, especially for certain subclasses including human IgG3, mouse IgG1 and rat IgG2a. Unlike protein A, protein G does not bind to human IgM, IgD and IgA.
