活性實(shí)驗(yàn)
Sphingomyelin phosphodiesterase 1 (SMPD1), also known as acid sphingomyelinase (ASM), belongs to the sphingomyelin phosphodiesterase family. The protein Converts sphingomyelin to ceramide. ASM also has phospholipase C activities toward 1,2-diacylglycerolphosphocholine and 1,2-diacylglycerolphosphoglycerol.
Thus, the recombinant human ASM activity was measured by its ability to hydrolyze 2-N-Hexadecanoylamino-4-nitrophenylphosphorylcholine (HDA-PC) to p-Nitrophenol. The reaction was performed in 50 mM MES, 0.5 μM ZnCl2, pH 7.5 ( Assay Buffer), initiated by addition 50 μL of various concentrations of ASM (diluted with Assay Buffer) to 50 μL of 1 mM Substrate HDA-PC ( 50 mM stock solution in methanol, diluted with Assay Buffer). Incubated at room temperature for 20 minutes in the dark, then read at a wavelength of 405 nm.
One unit of enzyme activity is defined as the 1μg of enzyme required to convert 1pmol of HDA-PC to p-Nitrophenol in 1min at 37°C. The specific activity of recombinant human ASM is >1000 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(chǔ)存
避免反復(fù)凍融。2-8°C不超過一個(gè)月,-80°C不超過12個(gè)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(yàn)決定,具體方法如下:在37°C孵育48小時(shí),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(chǔ),損失率低于5%。
