Long description
The reactivity of the antiserum is directed to the Fc and Fab subunits of the IgG molecule. It includes a certain degree of reactivity with other immunoglobulins via the common Fab portion. It does not react with any non-Ig protein in goat serum, as tested by immunoelectrophoresis and double radial immunodiffusion. To identify and measure IgG, antigen or antibody, at the cellular and subcellular level by immunofluorescence staining of appropriately treated cell and tissue substrates, and to demonstrate circulating antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen or immune complex using a reference antibody of goat origin in the middle layer of the indirect test procedure. As an extra step an avidin or streptavidin of the user’s choice has to be used. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions fir histochemical and cytochemical use are usually between 1:100 and 1:500; in ELISA and comparable no-precipitating antibody-binding assays between 1: 1,000 and 1:10,000.

Antibody s reacts with these species
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 been tested in double radial immunodiffusion with the following results: bovine ++ guinea pig ± mouse ± rat ± cat ± hamster - monkey + sheep ++ chicken - horse - pigeon - swine - dog ± human + rabbit ± turkey - A negative cross-reaction in double radial immunodiffusion does not exclude some reaction in more sensitive techniques.

Storage
The lyophilized conjugate 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, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the immunoconjugate. Lyophilized at +4° C--at least 10 years.Rreconstituted at or below -20° C--3-5 years. Reconstituted at +4° C--7 days

Description
This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.

Properties
If you buy Antibodies supplied by nordc they should be stored frozen at - 24°C for long term storage and for short term at + 5°C. Biotin conjugates can be detected by horseradish peroxidase, alkaline phosphatase substrates or anti biotin conjugated antibodies. Avidin and Streptavidin bind to the small biotin and are couple to HRP or AP for ELISA. To break the streptavidin Biotin bond we suggest to use a 6 molar guanidine HCl solution with acidity of pH 1.6.

About
Immunoglobulin gamma, IgG, mouse monoclonal H&L chain clones or rabbit, goat polyclonal antibodies have 4 parts. There are 2 heavy chains, 2 light chains. The IgG antibody has 2 antigen binding sites. They represent 70% or more of serum antibodies. This antibody can be antigen purified or protein A or G purified. For storage sodium azide is added or you can call us to request azide free antibody preparations. These will need colder storage temperatures.

Host
Goat, Donkeys or Equus africanus asinus are often used as host species to raise antibodies. Even Equus ferus or horse antibodies are different than donkey antibodies since we know horse anti donkey IgGs. For immunohistochemistry it is useful to use an anti-donkey or horse block if your primary antibody is a donkey anti-human. We provide also anti-donkey as a species antibodies and ELISA kits. The goat polyclonal antibodies are directed against human genes or rabbit or mouse IgGs (H +L) chain primary antibodies and conjugated for detection. It are very good secondary antibodies that are affinity purified and have a good affinity themselves too. Often KLH is coupled to the antigen so anti KLH can be present in the vial.
