Frequenin is a Ca2+ binding protein implicated in the regulation of neurotransmitter release at the neuromuscular junction. Frequenin amino acid sequences from different species appear closely related. In mouse a single 4.2 kbp mRNA is produced yielding a protein of 22kD when assayed by SDS-PAGE under reducing conditions. Frequenin may colocalize with the dendritic marker MAP-2 and is widely distributed in the brain, spinal cord and dorsal root ganglia. In Drosophila frequenin is related to recoverin and visinin and functions like Ca2+-sensitive guanylyl cyclase activator.
Applications:
Suitable for use in Immunofluorescence, ELISA and Western Blot. Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees 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.
