Transforming growth factor beta (TGFβ) family members are secreted in inactive complexes with a latency-associated peptide (LAP), a protein derived from the N-terminal region of the TGFβ gene product. Extracellular activation of these complexes is a critical step in regulation of TGFβ function in vivo. The TGFβ1 LAP is a ligand for the integrin αvβ6 and that αvβ6-expressing cells induce spatially restricted activition of TGFβ1. And LAP identifies a novel CD4+/CD25+ regulatory T cell subset with TGFbeta-mediated function and enhanced suppression of experimental autoimmune encephalomyelitis.

Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. |
Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
Stability & Storage |
Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted protein solutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
Shipping |
In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice. |
