活性實驗
Granzyme K is a member of the granzyme family of the serine proteases found specifically in the cytotoxic granules of cytotoxic T?lymphocytes (CTL) and natural killer (NK) cells. Human granzyme K is synthesized as a precursor (264?residues) with a signal peptide (residues 1 24), a propeptide (residues 25-26) and a mature chain (residues 27-264). The purified recombinant human Granzyme K consists of residues 27 to 264 which activity was measured by its ability to cleaves a thioester substrate Z-Lys-SBzl?HCl. The reaction was performed in 0.05 M Tris, 0.15 M NaCl, 0.01% Triton X-100, pH 8.0 (assay buffer), initiated by addition 50 μL of various concentrations of GZMK (diluted by assay buffer) to 50 μL of 1.2 mM substrate and DTNB mixture. The final well serves as a negative control with no GZMK, replace with 50 μL assay buffer. Incubated at 25℃ for 5min, then read at a wavelength of 405 nm. The specific activity of recombinant human Granzyme K is >220 pmol/min/μg.
用法
Reconstitute in 10mM PBS (pH7.4) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
儲存
避免反復(fù)凍融。2-8°C不超過一個月，-80°C不超過12個月。
穩(wěn)定性
熱穩(wěn)定性以損失率顯示。損失率是由加速降解試驗決定，具體方法如下：在37°C孵育48小時，沒有顯著的降解或者沉淀產(chǎn)生。保質(zhì)期內(nèi)，在適當(dāng)?shù)臈l件下存儲，損失率低于5%。
