Background for Phosphoserine phosphatase

Phosphoserine phosphatase fills an important role in the biosynthesis of serine from carbohydrates by catalyzing the last step, hydrolysis of O-phosphoserine. Phosphoserine phosphatase activity in lymphoblasts and fibroblasts was reduced to 25% of normal values. The human phosphoserine gene(PSP)is mapped to the pter-q22 region of chromosome 7.

Customer Q&As

Q: Is your western blot protocol provided from the website applicable for all your antibodies? Keyword: applications, WB
A: The protocol is applicable for all our antibodies in WB, the NC Membrane(0.45μm or 0.22μm) and transfer time(70 mins or 50 mins) depends on the protein molecular weight, details can be found in included protocol.
Q: Can I conjugate markers to this antibody? Can I link custom conjugates to this antibody? Keyword: conjugation
A: The antibody is stored with BSA and cannot be conjugated with markers. Carrier free antibodies are available upon request. Please contact
Q: Can you provide monoclonal antibodies carrier free?
A: We cannot.
