Members of the Smad family of cell signaling molecules are components of a critical intracellular pathway that transmit TGF-β signals from the cell surface into the nucleus. There are three distinct classes of Smads: the receptor-regulated Smads (R-Smads), the common-mediator Smad (co-Smad), and the antagonistic or inhibitory Smads. Following stimulation by TGF-β, Smad2 and Smad3 become phosphorylated at their carboxyl termini (Ser465 and 467 on Smad2; Ser423 and 425 on Smad3) by TGF-β Receptor I. Phosphorylated Smad 2/3 can complex with Smad4, translocate to the nucleus and regulate gene expression.
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.Rabbits are used for polyclonal antibody production by StressMark antibodies. Rabbit antibodies are very stable and can be stored for several days at room temperature. StressMark antibodies adds sodium azide and glycerol to enhance the stability of the rabbit polyclonal antibodies. Anti-human, anti mouse antibodies to highly immunogenic selected peptide sequences are" monoclonal like" since the epitope to which they are directed is less than 35 amino acids long.
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.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.
