Recombinant Human MSLN Protein, hFc-tagged, Alexa Fluor 555 conjugated

• Cat.No.: MSLN-340HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human MSLN (Glu296-Gly580) protein was fused to human IgG1 Fc tag at N-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: Mesothelin (MSLN) is also known as CAK1 antigen, Pre-pro-megakaryocyte-potentiating factor, which belongs to the mesothelin family. Mesothelin/MSLN can be proteolytically cleaved into the following two chains by a furin-like convertase: Megakaryocyte-potentiating factor (MPF) and the cleaved form of mesothelin. Both MPF and the cleaved form of mesothelin are N-glycosylated. Mesothelin/MSLN can interacts with MUC16. The membrane-anchored forms of MSLN may play a role in cellular adhesion. MPF potentiates megakaryocyte colony formation in vitro.
• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized
• Molecular Mass: The protein has a calculated MW of 59.6 kDa. As a result of glycosylation, the protein migrates as 60-68 kDa under reducing (R) condition, and 120-130 kDa under non-reducing (NR) condition (SDS-PAGE).
• Protein length: Glu296-Gly580
• N-terminal Sequence Analysis: Glu 296
• Endotoxin: < 1.0 EU/ μg by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 555 via amines
  With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Storage Buffer: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
