Product Details
- Molecular Aliases
- CEDLAP; DPD1; TGF beta1; TGFB; TGFB1; TGFbeta; TGF-beta-1; TGF β1; TGFβ; TGF-β-1;TGF b1; TGF beta 1; TGF beta; TGF-b-1; TGF-b1
- Protein Length
- Ala279-Ser390
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 13.2 kDa. Due to glycosylation, the protein migrates to 15-18 kDa under reduced (R) condition and 26-30 kDa under Non reduced (N) condition based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22μm filtered solution in 50mM Glycine, 150mM NaCl (pH 2.5). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in 4mM HCL. Please refer to the Certificate of Analysis for detailed instructions.

Background
TGF-beta 1 (transforming growth factor beta 1) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cystine knot structure. TGF-beta 1, -2 and -3 are highly pleiotropic cytokines that are proposed to act as cellular switches that regulate processes such as immune function, proliferation and epithelial-mesenchymal transition.Transforming growth factor beta-1 is multifunctional protein that regulates the growth and differentiation of various cell types and is involved in various processes, such as normal development, immune function, microglia function and responses to neurodegeneration.
