Human CellExpTM Granzyme B, human recombinant

Catalog#: 7233-10
Size: 10 μg
Price: 5325 (RMB)

Product Name: Human CellExp™ Granzyme B, human recombinant

Alternate Name/Synonyms: GZMB, CCPI, CGL-1, CGL1, CSP-B, CSPB, CTLA1, CTSGL1, HLP, SECT, Fragmentin-2, Granzyme B, Granzyme-2, GRB

Gene Symbol: GZMB

Accession #: P10144

Gene ID: 3002

Source: HEK 293 cells

Appearance: Lyophilized powder

Physical Form Description: Lyophilized from 0.22 μm filtered solution in PBS. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.

Molecular Weight: The protein is fused with 6×His tag at the C-terminus, has a calculated MW of 26.4 kDa. The predicted N-terminus is Thr 21. DTT-reduced Protein migrates as 35 kDa due to glycosylation.

Purity by SDS-PAGE: ≥95%

Purity by HPLC: N/A

Endotoxin Level: < 0.1 ng/μg of protein (<1EU/μg).

Biological Activity: Measured by its ability to cleave a peptide substrate, t-Butyloxycaronyl-Ala-Ala-Asp-ThioBenzyl ester (Boc-AAD-SBzl), in the presence of 5, 5’-Dithio-bis (2-nitrobenzoic acid) (DTNB). The specific activity is more than 800 pmol/min/µg.

Reconstitution Instructions: 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°C for up to 1 month. For extended storage, it is recommended to store at -20°C.

Storage Temp.: -20°C

Shipping: Gel pack

Background Information: Granzyme B (GZMB) also known as Cathepsin G-like 1 (CTSGL1), Cytotoxic T-lymphocyte proteinase 2 (Lymphocyte protease), Fragmentin-2, Granzyme-2, Human lymphocyte protein (HLP), SECT, CGL1, CSPB, CTLA1, GRB, which belongs to the peptidase S1 family. Granzyme subfamily GZMB / CTSGL1 contains 1 peptidase S1 domain. The catalytic activity of Granzyme B is “Preferential cleavage: -Asp-|-Xaa- >> -Asn-|-Xaa- > -Met-|-Xaa-, -Ser-|-Xaa-“, and is inactivated by the serine protease inhibitor diisopropyl fluorophosphates. GZMB is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. GZMB seems to be linked to activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution and cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis.

Amino Acid Sequence: N/A

Handling: Centrifuge the vial prior to opening
