Product Name Sheep Serum Against Human IgG4
Catalog Number orb22440
Species/Host Sheep
Conjugation Unconjugated
Tested applications DOT, IEP
Immunogen Purified homogenous IgG4 is isolated from human serum. Freunds complete adjuvant is used in the first step of the immunization procedure.
Target IgG4. The activity of the antiserum is directed to human IgG4 subclass. It does not react with any non-Ig protein in human serum, as tested by immunoelectrophoresis and double radial immunodiffusion.
Form/Appearance Vials with 1 ml lyophilized antiserum.
Concentration Total protein and IgG concentration in the antiserum are comparable to those of pooled sheep serum. No foreign proteins added.
Preservatives No preservative added, as it may interfere with the antibody activity. No foreign protein added.
Storage The lyophilised antiserum is shipped at ambient temperature and may be stored at 4°C; prolonged storage at or below -20°C. It is reconstituted by adding 1 ml sterile distilled water. 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 product.
Note For research use only.
Clonality Polyclonal
Adsorption Immunoaffinity adsorption with insolubilized highly purified myeloma proteins of the other subclass or other serum proteins as required.
Application Notes Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.

IE: Because of their characteristics and those of the subclass-specific antigenic determinants, the use of these antisera requires special precautions. Their specificity and reactivity depend largely on the conditions of the test system in which they are applied. The performance of Biorbyt polyclonal subclass-specific antisera is guaranteed when they are used for the purposes described, applying the special immunoprecipitation arrangement recommended for these purposes. In immunoelectrophoresis use 2 μl 1:8, 1:16 and 1:32 dilutions of pathological serum or equivalent against 60 μl antiserum. In double radial immunodiffusion use a rosette arrangement with 10 μl antiserum in 3 mm diameter center well and 2 μl serum samples (neat and serially diluted) in 2 mm diameter peripheral wells. Biorbyt also makes available a human standard serum with assigned values of the subclasses of IgG (orb80208).
