Clone Host Grade Applications
Polyclonal Sheep Affinity Purified B
JAM-4, also known as IGSF5, is a 93kD member of the CTX (Cortical Thymocyte Marker in Xenopus) subfamily of the Ig superfamily. It is a type I transmembrane protein with an N-terminal extracellular V-type and C2 type Ig domain separated by a J segment, a transmembrane domain and a cytoplasmic tail with a PDZ binding motif. JAM-4 is expressed in intestinal, renal, and mammary epithelial cells, spermatogonia, and hematopoietic stem cells. It is a cell adhesion molecule that mediates homophilic interaction. JAM-4 also interacts with the intracellular membrane-associated guanylate kinase inverted 1 (MAGI-1). An additional isoform containing a 100 residue insertion between Gln 125 and Asp 126 has been reported. Over the region used as immunogen, mouse JAM-4 shares 82% and 63% amino acid sequence identity with rat and human JAM-4, respectively.
Catalog #J8009-30
ApplicationsWestern Blot: This antibody can be used at 0.1-0.2ug/ml with the appropriate secondary reagents to detect recombinant mouse JAM4. The detection limit for rmJAM4 is approximately 5 ng/lane under non-reducing and reducing conditions. In this format, this antibody shows less than 1% crossreactivity with rmJAM-A, rmJAM-B, and rmJAM-C.
Optimal dilutions should be determined by each laboratory for each application.
Storage and StabilityLyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile TBS with 40-50% glycerol and store at -20°C. Reconstituted product is stable for 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.
Clone TypePolyclonal
