Kallikrein-11 human

NA.32

Kallikrein 11 (KLK11) is also known as Hippostasin, Serine protease 20, Trypsin-like protease, PRSS20, TLSP, which belongs to the peptidase S1 family and Kallikrein subfamily. KLK11 contains one peptidase S1 domain. KLK11 is expressed in brain, skin and prostate. Isoform 1 is expressed preferentially in brain. Isoform 2 is expressed in prostate. Present in seminal plasma at concentrations ranging from 2 to 37 μg/mL (at protein level). Kallikrein 11 /KLK11 is a possible multifunctional protease and efficiently cleaves ′bz-Phe-Arg-4-methylcoumaryl-7-amide′, a kallikrein substrate, and weakly cleaves other substrates for kallikrein and trypsin. KLK11 cleaves synthetic peptides after arginine but not lysine residues.

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 2 mM CaCl2, 150 mM NaCl, pH 7.5. Normally Mannitol or Trehalose is added as protectants before lyophilization.

Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8℃ for up to 1 month. For extended storage, it is recommended to store at -20℃.
