The antiserum does not cross-react with any other monkey plasma proteins as tested in gel-diffusion techniques. Inter-species cross-reactivity is a normal feature of antibodies to plasma or milk proteins, since homologous proteins of different species frequently share antigenic determinants. of this antiserum has not been tested in detail.

Precipitating polyclonal goat antiserum to monkey lactoferrin
Aufreinigung
Adsorption: Immunoaffinity adsorbed using insolubilized fractions of monkey serum and lactoferrin-depleted monkey milk as required, to eliminate antibodies reacting with other monkey serum or milk proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
Immunogen
Exocrine organs produce various secretions, each with its characteristic function. Proteins found in secretions may be divided into two groups: those specific for the particular secretion, and plasma proteins independent of the type of exocrine cells. Lactoferrin belongs to the first group. It is an iron containing protein with a molecular weight of 75,000 and it is antigenically different from transferrin. Lactoferrin has a slight antimicrobal action. Originally identified in milk, its presence has also been demonstrated in other secretions as saliva, semen and tears. The immunogen has been isolated from rhesus monkey milk. Freund’s complete adjuvant is used in the first step of the immunization procedure.
In precipitating techniques as immunoelectrophoresis, single and double radial immunodiffusion Mancini, Ouchterlony)and electroimmunodiffusion (Laurell) for the identification and quantitative determination of lactoferrin in body fluids.

Konzentration
Total protein and IgG concentration in the antiserum are comparable to those of pooled normal goat serum. No foreign proteins added. Antibody titre: Precipitin titre not less than 1:16 when tested against normal monkey milk in agar block immunodiffusion t
The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C, prolonged storage at or below -20°C. Reconstitute the lyophilized antiserum by add ing 1 ml sterile distilled water. 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 centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4°C, not refrozen, and preferably used the same da y.
Tested in immunoelectrophoresis against monkey milk a single precipitin line is obtained. The antiserum does not react with any other protein component of monkey serum or plasma
