PIVKA II (2D7), mAb, Mouse
$33,292.50 Add to cart View Product DetailsProtein Induced by Vitamin K Absence or Antagonist-II (PIVKA-II), also known as Des-γ-carboxy-prothrombin (DCP), is an abnormal form of prothrombin. Normally, the prothrombin’s 10 glutamic acid residues (Glu) in the γ-carboxyglutamic acid (Gla) domain at positions 6, 7, 14, 16, 19, 20,25, 26, 29 and 32 are γ-carboxylated to Gla by vitamin-K dependent γ- glutamyl carboxylase in the liver and then secreted into plasma. In patients with hepatocellular carcinoma (HCC), γ-carboxylation of prothrombin is impaired so that PIVKA-II is formed instead of prothrombin. PIVKA-II is considered as is an efficient biomarker specific for HCC.

PreScission Protease
$76.76 Add to cart View Product DetailsPreScission Protease is a fusion protein of glutathione S-transferase (GST) and human rhinovirus (HRV) type 14 3C protease. The optimum recognition site for this enzyme is the sequence Leu-Glu-Val-Leu-Phe-Gln/Gly-Pro (LEVLFQ/GP) and cleavage occurs between the Gln and Gly-Pro residues. Substrate recognition and cleavage are likely to be dependent not only upon primary structural signals, but also upon the secondary and tertiary structures of the fusion protein as well.

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.

Protein G Resin FF
$1,905.26 Add to cart View Product DetailsGenScript Protein G Resin FF is an affinity chromatography medium designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. The recombinant protein G ligand is coupled to 4% highly cross-linked agarose. The static binding capacity of Protein G Resin FF is greater than 20 mg human IgG/ml settled resin. The dynamic binding capacity will vary depending on several factors such as target antibody, flow rate etc. Table 1 lists the characteristics of Protein G Resin FF.
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 L Resin
$138.00 Add to cart View Product DetailsGenScript Protein L Resin is an affinity chromatography medium designed
for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. The highly purified protein L ligand is
coupled to 4% agarose. The coupling is
optimized to give high binding capacity for immunoglobulins.
The static binding capacity of Protein L Resin is greater than 15 mg rabbit IgG/ml settled resin. The dynamic binding capacity will vary depending
on several factors such as target antibody, flow rate etc.Protein L, first isolated from the surface of
bacterial species Peptostreptoccus magnus,
binds immunoglobulin through κ light chain interaction. Protein L binds a wider
range of Ig classes and subclasses than other antibody-binding proteins such as
protein A or protein G. It can bind to all classes of Ig (i.e., IgG, IgM, IgA,
IgE, and IgD) and also the single chain variable fragments (Scfv) and Fab
fragments. -
