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.
Background information
Catalyzes the transfer of sulfate to beta-1,3-linked galactose residues in O-linked glycoproteins. Good substrates include asialofetuin, Gal-beta-1,3-GalNAc and Gal-beta-1,3 (GlcNAc-beta-1,6)GalNAc.
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.
Cross Reactive Species details
No significant cross reactivity has been observed for this antibody for the tested species. However, note that due to limited knowledge it is impossible to predict with 100% guarantee that the antibody does not corss react with any other species.
Advisory
Avoid freeze/thaw cycles as they may denaturate the polypeptide chains of the antibody, thus reducing its reactivity, specificity and sensitivity. For antibodies that are in liquid form or reconstituted lyophilized antibodies small amounts could become entrapped on the seal or the walls of the tube. Prior to use briefly centrifuge the vial to gather all the solution on the bottom.
Properties
For facs or microscopy Alexa 1 conjugate.Alexa Fluor 488 has the same range to that of fluorescein isothiocyanate (FITC), yet the Anti-GAL3ST4 ALEXA FLUOR® 488 has a very high photo stability. As a result of this photo stability, it has turned into an antibody for fluorescent microscopy and FACS FLOW cytometry. It is distinguished in the FL1 of a FACS-Calibur or FACScan. Also Alexa Fluor 488 is pH stable.
