For facs or microscopy Alexa 1 conjugate.Alexa Fluor 488 has the same range to that of fluorescein isothiocyanate (FITC), yet the Anti-MSK1 Thr581 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.If you buy Antibodies supplied by Bioss Primary Conjugated Antibodies. ALEXA FLUOR they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Background of the antigen
MSK1 is a mitogen and stress activated protein kinase 1 which belongs to the AGC family of kinases and is related in structure to the ribosomal p70 S6 kinase subfamily. MSK1 can be activated by ERK1/2 and SAPK2/p38 MAP kinase. It is also known to be required for the phosphorylation of CREB, ATF1 H3 and HMG14 in response to mitogen and stress. Similar to RSK, MSK1 contains two kinase domains (N term and a C term). Once phosphorylated on Thr581 and Ser360 by ERK1/2 and SAPK2/p38, MSK1 autophosphorylate on at least 5 sites. Of these autophosphorylation sites Ser212 and Ser376 get phosphorylated by the C terminal kinase domain of MSK1 which is essential for the catalytic activity of the N terminal kinase domain.
