Goat anti Human thyroxine binding globulin

The reactivity of the antiserum is restricted to thyroxine binding globulin. In immunoelectrophoresis and radial immunodiffusion (Ouchterlony), using various antiserum concentrations against fresh normal Human plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified thyroxine binding globulin. No reaction is obtained with any other plasma protein component or serum. In precipitating techniques as immunoelectrophoresis and single or double radial immunodiffusion to identify the presence of thyroxine binding globulin in Human plasma or other body fluids or to determine its concentration. The presence of non-precipitating antibodies has not been assayed. This does not exclude the use in non-precipitating antibody-binding techniques if proper controls are included.

Thyroxine binding is a protein with a molecular weight of 55,700 kD. The protein is binding thyroxine as well as triiodothyronine. In immunoelectrophoresis it has a alpha mobility. The mean concentration in normal Human serum is about 40 μg/mL. Elevated levels are observed during oestrogen administration, pregnancy hypothyroidism. Reduced levels are observed in hypothyroidism. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Precipitation assays. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifµgation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4°C, not refrozen, and preferably used the same day.

Delipidated, heat inactivated, lyophilized, stable whole antiserum; No preservative added Total protein and IgG concentrations in the antiserum are comparable to those of pooled; Normal goat serum; No foreign proteins added._x000D_ Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water
