Tryptases are enzymatically active only as heparin-stabilized tetramers, and they are resistant to all known endogenous proteinase inhibitors. Several tryptase genes are clustered on chromosome 16p13.3. These genes are characterized by several distinct features. They have a highly conserved 3' UTR and contain tandem repeat sequences at the 5' flank and 3' UTR which are thought to play a role in regulation of the mRNA stability. These genes have an intron immediately upstream of the initiator Met codon, which separates the site of transcription initiation from protein coding sequence. This feature is characteristic of tryptases but is unusual in other genes. The alleles of this gene exhibit an unusual amount of sequence variation, such that the alleles were once thought to represent two separate gene\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, ELISA\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthesized peptide derived from part region of human protein AA range: 200-250\u003c\/p\u003e\n\n\u003cp\u003eIsotype: IgG\u003c\/p\u003e\n\n\u003cp\u003eTarget: Mast cell tryptase\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: TRYB1 Polyclonal Antibody detects endogenous levels of protein.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB 1:500-2000 ELISA 1:5000-20000\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.\u003c\/p\u003e\n\n\u003cp\u003eConcentration: 1 mg\/ml,\u003c\/p\u003e\n\n\u003cp\u003eFormlation: Liquid in PBS containing 50% glycerol, and 0.02% sodium azide.\u003c\/p\u003e\n\n\u003cp\u003eExpression: Isoform 1 and isoform 2 are expressed in lung, stomach, spleen, heart and skin, in these tissues, isoform 1 is predominant, Isoform 2 is expressed in aorta, spleen, and breast tumor, with highest levels in the endothelial cells of some blood vessels surrounding the aorta, as well as those surrounding the tumor and low levels, if any, in mast cells (at protein level),\u003c\/p\u003e\n\n\u003cp\u003eObserved Band (KD): 30kD\u003c\/p\u003e\n\n\u003cp\u003eFields: Influenza A\u003c\/p\u003e\n\n\u003cp\u003eFunction: Catalytic Activity: Preferential cleavage: Arg-|-Xaa, Lys-|-Xaa, but with more restricted specificity than trypsin\u003cbr\u003e\nFunction: Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type\u003cbr\u003e\nFunction: Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type.
