Extra Details:: The cyclic nucleotides cAMP and cGMP are implicated in signal transduction events such as the visual transduction, relaxation of smooth muscles, intestinal secretion of water and salt, reabsorption of Na+ and water in the distal tubule of the nephrons. cAMP/cGMP activate Ca2+ -permeable ion channels called cyclic nucleotide-gated channels (CNG or CNC). Activation of CNG leads to depolarization of the membrane voltage and to a concomitant increase of the cytosolic Ca2+. CNG consists of two distinct subunits, designated a and b subunits. Several CNG a-subunits (CNG alpha 1-3) & beta subunits (subunit 2 or CNGb1-2 or CNG4-5) and numerous isoforms. a-subunit can form functional channel by themselves, whereas, b-subunits modulate the channel property of a-subunits. CNG display intracellular N and C-termini, 6 transmembrane domains or segments (S1-S6). The region between S5 and S6 contains the ion-conducting pore (P). The cyclic nucleotide-binding region is found at the c-terminus. Native functional CNG may exists as heteromultimer containing some combination of a, and b subunits. Bovine CNG1 was initially cloned and characterized from rod cells. CNG1 (rat 683 aa, mouse 684, human 686 aa; also describes as OCNC1) is primarily expressed in outer segment of photoreceptor rod cells, and in a variety of tissues (kidney, eye, pineal gland, pituitary, adrenal, spleen, brain, heart, skeletal muscle, and testis). Human/mouse CNG1 exhibit ~88% sequence homology. Applications: Suitable for use in ELISA. Western Blot, though not tested, may potentially be used as an application. Other applications not tested. Recommended Dilutions: ELISA: 0.5-1ug/ml Control peptide (C5999-25) can be used to coat ELISA plates at 1ug/ml. Western Blot: 1-10ug/ml using ECL. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -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.
