Specifications

C-DLHTLSEDSYKDST, from the internal region of human Stratifin.
Control peptide corresponding to polyclonal antibody, Catalog#S7973-69C, goat x human.
Catalog #S7973-69C-P
Members of the 14-3-3 family of proteins are highly conserved proteins, localized in neurons, and are axonally transported to the nerve terminals. They are also present, at lower levels, in various other eukaryotic tissues. 14-3-3 proteins appear to play important roles in a variety of signal transduction pathways, including those involved in cell cycle regulation and cell survival. As 14-3-3 proteins bind to specific phosphoserine-containing sequences they are likely to have an important role in signaling pathways mediated by serine/threonine protein kinases. 14-3-3 sigma may be required for Raf-1 kinase activity and phosphorylation, among many other functions.
ApplicationsSuitable for use in ELISA. Other applications not tested.
Recommended DilutionsOptimal dilutions to be determined by the researcher
Positive ControlHuman Skin lysates
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C. Aliquots are stable for at least 12 monthsat -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Peptide Blocking (see corresponding antibody S7973-69C)Antibodies are typically supplied at 0.5mg/ml and peptides as a 100ul pellet. When peptides are reconstituted in 200ul water, the concentration would be also 0.5mg/ml. To start, the best ratio would be 1:1 (which means molar excess of peptides relative to antibodies when identical volumes are mixed). Mix equal volumes of peptide and antibody at the required dilution and leave at ambient temperature. It is best is to have two identical blots, to be incubated with equal amount of antibodies, but one with the antibodies pre-adsorbed to the peptide for 20min. Then incubate and develop the two blots in parallel.
