KLKB1 Protein, Human, Recombinant (His)

Plasma kallikrein, also known as Fletcher factor or kallikrein B1 (KLKB1), is a serine endopeptidase, like its homologs tissue kallikrein and kallikrein-related peptidases (KLKs). Its physiological role is to catalyze the release of kinins and other vasoactive peptides. KLKB1 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 70.3 kDa and the accession number is P03952.

Description

Species	Human
Expression System	HEK293 Cells
Tag	C-His
Accession Number	P03952
Synonyms	PKK, Kininogenin, KLK3, KLKB1, Fletcher factor, Plasma kallikrein
Construction	Gly20-Ala638
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	70.3 kDa (predicted). Due to glycosylation, the protein migrates to 72-80 kDa based on Tris-Bis PAGE result.

Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM NaAc, 150 mM NaCl (pH 5.0). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in 20mM NaAc,150mM NaCl (pH 5.0). The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted protein solutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
