Species | Human |
Tag | C-His-Avi |
Expression Systems | Expi293 |
Keywords | Human; C-His-Avi; Expi293 |
Synonyms | MSLN; CAK1; Mesothelin; MPF; MPFSMRP; SMR |
Background | Mesothelin, also known as MSLN, is a protein that in humans is encoded by the MSLN gene. Cloning studies showed that the mesothelin gene encodes a precursor protein that is processed to yield mesothelin which is attached to the cell membrane by a glycophosphatidylinositol linkage and a 31 kDa shed fragment named megakaryocyte-potentiating factor (MPF). Although it has been proposed that mesothelin may be involved in cell adhesion, its biological function is not known. A knockout mouse line that lacks mesothelin reproduces and develops normally. |
Source | Recombinant Human MSLN/Mesothelin Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Glu296-Gly580. |
Molecular Weight | The protein has a predicted MW of 35.2 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. |
Endotoxin | Less than 1 EU per μg by the LAL method. |
Purity | >95% as determined by Tris-Bis PAGE. >95% as determined by HPLC. |
Formulation | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
Reconstitution | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage | -20 to -80℃ for 12 months as supplied from the date of receipt. -20 to -80℃ for 3-6 months in an unopened state after reconstitution. 2-8℃ for 2-7 days after reconstitution. |
Notes | Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. |
