Synaptic adhesion-like molecule 2 (SALM2; also leucine-rich repeat and fibronectin type-III domain-containing protein 1 (Lrfn1) is a 105kD member of the Lrfn family of type I transmembrane glycoproteins. Human SALM2 is synthesized as a 771aa precursor that contains a 31aa signal sequence, a 505aa extracellular domain, a 21aa transmembrane region, and a 214aa cytoplasmic region. The ECD consists of seven leucine-rich repeats, an IgC2-like domain, and a fibronectin type-III domain, tandemly aligned in that order. In addition, there are two potential sites for N-linked glycosylation. The C-terminal region contains an intracellular PDZ binding domain, which is conserved among SALMs 1-3, but is absent in SALMs 4 and 5. Mature human SALM2 shares 96% and 95% sequence identity with mature mouse and rat SALM2, respectively.
Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.
Recommended Dilution:
ELISA: 0.5-1ug/ml
Western Blot: 1ug/ml
Optimal dilutions to be determined by the researcher.
Storage and Stability:
Lyophilized powder may be stored at -20 degrees C for short-term only. Reconstitute with sterile 40-50% glycerol, aliquot and store at -20 degrees C. Reconstituted product is stable for 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.
