1. Product introduction
Â
Streptococcus Protein G (SPG for short) is a protein in the cell
wall of G and C streptococci. It can specifically bind to the Fc
segment of immunoglobulin IgG molecules without affecting the
ability of its Fab segment to bind to antigen molecules. It can
not only bind to all subclasses of human, mouse, and rat IgG, but
can also bind to guinea pig, rabbit, goat, cow, sheep, and horse
IgG, which is significantly better than only binding to human and
mouse IgG. Staphylococcus protein A (Staphylococcus Protein A,
referred to as SPA). In addition to the IgG binding domain,
natural SPG also has albumin and cell surface binding domains.
Recombinant SPG removes albumin and cell surface binding domains
to reduce non-specific binding. It has a greater affinity than
natural SPG and SPA.

3. Storage and transportation stability
Storage stability: Recombinant protein G freeze-dried powder is
stored at **0℃, stable
for *0 months; after dissolving, put it on an ice bath and use it
as soon as possible. If you need to use it multiple times, please
store it at **5℃
before use. , Avoid repeated freezing and thawing affecting
protein activity.
Transport stability: Blue ice is transported under heat
preservation and has stable activity.
4. Product use
SPG is extremely versatile, and can be used to separate and
purify or remove IgG from serum, the purification of monoclonal
antibodies, and the separation of antigen-antibody complexes.
After SPG is combined with agarose gel, affinity fillers for
antibody purification can be prepared to separate and purify IgG
of different subtypes from serum, ascites, cell culture
supernatant, etc.
