Contact our support service to receive datasheet or other technical documentation.
StressMark antibodies supplies antibodies that are for research of human proteins.
Antibody's recommended dilutions for use
WB (1:1000), ELISA (1:10000); optimal dilutions for assays should be determined by the user.
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.
Certificate of analysis
A 1:1000 dilution of SPC-1286 was sufficient for detection of Smad4 in 10 µg of HeLa, Cos7, HepG2, HUVEC cell lysates by ECL immunoblot analysis using Goat Anti-Rabbit IgG:HRP as the secondary antibody.

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.
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. Smad4 mediates all activities through interaction with various other Smad family members.

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.
