Human MSLN/Mesothelin Gene, Full-length cDNA in Lentivector, Endotoxin-free DNA

Description

Mesothelin (MSLN) is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that is expressed on mesothelial cells in the pleura, pericardium and peritoneum.  It is overexpressed in mesotheliomas, ovarian and pancreatic cancers as well as in specific squamous cell carcinomas. The MSLN gene encodes a precursor protein that is cleaved into two products, megakaryocyte-potentiating factor (MPF) and MSLN. MPF is secreted and functions as a cytokine that can stimulate colony formation in bone marrow megakaryocytes. The cleaved form of MSLN remains GPI-anchored on cell-surface and may function as a cell adhesion molecule. Alternative splicing results in multiple transcript variants. Two variant forms exist; variant 1 has an eight amino acid insertion and is rarely expressed, while variant 2 is a truncated form found in cancers but rarely detected in normal individuals. MSLN interacts with CA125/MUC16 and potentiates megakaryocyte colony formation in vitro. MSLN is secreted by several mesothelioma cell lines and is frequently elevated in the blood of patients with mesothelioma. Measurement of this protein may be useful in following the response of mesothelioma to treatment. 

 

 

Gene Symbol: MSLN; MPF; SMRP; CAK1

 

NCBI Gene ID: 10232

 

Uniprot Entry: Q13421

 

Construct Details: Full length human MSLN gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter -/+ an antibiotic selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles.

 

Vector Type: pLTC or pLTC-Marker (see the vector map above)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
