Human SMPD1 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human SMPD1 Protein is expressed from Baculovirus-Insect Cells with His tag at the C-terminus.
It contains Met1-Pro628 [Accession | NP_000534.3].

分子量大小(Molecular Weight)

The protein has a predicted MW of 66.53 kDa. Due to glycosylation, the protein migrates to 67-70 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

制剂(Formulation)

Supplied as 0.22 μm filtered solution in 20mM Tris, 500mM NaCl, 25% glycerol (pH 7.5).

存储(Storage)

Valid for 12 months from date of receipt when stored at -80°C.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

Human SMPD1 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human SMPD1 is greater than 95% as determined by SEC-HPLC.

Bioactivity Data

Measured by its ability to cleave 2-N-Hexadecanoylamino-4-nitrophenylphosphorylcholine (HNPPC). The specific activity is > 1500 pmol/min/μg, as measured under the described conditions.

背景(Background)

Sphingomyelin phosphodiesterase 1 (SMPD1) converts sphingomyelin into ceramide and phosphocholine; hence, loss of SMPD1 function causes abnormal accumulation of sphingomyelin in lysosomes, which results in the lipid-storage disorder Niemann-Pick disease (types A and B). SMPD1 activity is dependent on zinc, which is coordinated at the active site of the enzyme.

分子别名(Synonyms)
