Polyclonals and antibodies
Sequence of the immunogen: Smad4 (Trp323~Asp552); Buffer composition: PBS, pH7.4, containing 0.02% NaN3, 50% glycerol.
Upon receipt, store at -20°C or -80°C. Prepare working aliqotes prior to storage to avoid repeated freeze-thaw cycles.
A Rabbit polyclonal antibody against Human Mothers Against Decapentaplegic Homolog 4 (Smad4). This antibody is labeled with HRP.
Host: Rabbit; Species Reactivity: Human; Clonality: polyclonal; Tested applications: WB, IHC; Concentration: 500ug/ml; Isotype: IgG; Conjugation: HRP
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.
If you buy Antibodies supplied by Cloud Clone Corp they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.HRP conjugates are often primary rabbit polyclonal antibodies couples to the enzyme horseradish peroxidase (HRP), found in the roots of horseradish. Also monoclonal HRP conjugates are often used for Western Blot.Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
