Goat IgG Fc Fragment
Gallus gallus domesticus and other IgY antibodies have high affinity and are easy to collect from the yolk. Gallus gallus can produce 20 more than in rabbit polyclonal. The antibody will not bind to rheumatoid factor or protein or Fc regions. This gives very much reduced background very much suited for diagnostic applications. Papain will digest IgY’s to divalent Fab antibody fragments. IgY’s are suited for Elisa kit development, Immunohistochemistry and Western Blot.
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.
If you buy Antibodies supplied by gallus IgY they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.Chickens like all bird species have IgY antibodies that are very stable and found in the yolk. Gallus Gallus domestica is the Latin name of the Chicken.
Antibody fragments and scFv fragments, single chain variable fragments can be E. coli expressed. Fragment peptides for polyclonals give monoclonal like antibodies as the epitope is very small. IgG Fc and(ab)2 fragments are small and stable subunits of the antibody obtained by enzymatic digestion. Complement fragments, bp DNA fragments are common.IgG

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.Polyclonals can be used for Western blot, immunohistochemistry on frozen slices or parrafin fixed tissues. The advantage is that there are more epitopes available in a polyclonal antiserum to detect the proteins than in monoclonal sera.
