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.

Certificate of analysis

A 1:1000 dilution of SPC-1284 was sufficient for detection of Smad2 in 10 µg of Hek293 cell lysates by ECL immunoblot analysis using Goat Anti-Rabbit IgG:HRP as the secondary antibody.

Scientific context

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.

About

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.

Properties

This StressMark antibodies Fluorescein isothiocyanate (FITC) antibody is currently after some BD antibodies the most commonly used fluorescent dye for FACS. When excited at 488 nanometers, FITC has a green emission that's usually collected at 530 nanometers, the FL1 detector of a FACSCalibur or FACScan. FITC has a high quantum yield (efficiency of energy transfer from absorption to emission fluorescence) and approximately half of the absorbed photons are emitted as fluorescent light. For fluorescent microscopy applications, the 1 FITC is seldom used as it photo bleaches rather quickly though in flow cytometry applications, its photo bleaching effects are not observed due to a very brief interaction at the laser intercept. StressMark antibodies FITC is highly sensitive to pH extremes.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.
