Gc-globulin is a plasma protein produced in the liver. Amongst its ligands are vitamin D, thus Gc-globulin is also called vitamin D-binding protein. Gc-globulin is furthermore part of the actin scavenging system, binding and removing monomeric actin from the blood stream. The molecular mass of Gc-globulin is approximately 50 kDa. The concentration of Gc-globulin in human plasma is app. 400 µg/ml (1).
Gc-globulin isolated from human plasma adsorbed onto aluminum hydroxide gel
HYB 249-01 is specific for human Gc-globulin.
Epitope specificity differs from that of HYB 249-02, HYB 249-05 and HYB 249-10.
HYB 249-01 reacts strongly with Gc-globulin. In order to measure actin-free Gc-globulin a combination of HYB 249-05 as capture antibody and HYB 249-01B as biotinylated detection antibody can be used. A strong reaction is alco seen in ELISA with Gc-globulin coated directly onto the microtiter well and when tested in sandwich ELISA in combination with a polyclonal antibody against Gc-globulin (e.g. DAKO A0021).
In Western blotting after SDS-PAGE, HYB 249-01 reacts with Gc-globulin in both reduced as well as unreduced forms.
