- Description
- Description: This VB3A9 monoclonal antibody recognizes human latency-associated peptide (LAP), also known as the TGF-beta propeptide. Human LAP is a homodimer of 65-75 kDa that is non-covalently associated with TGF-beta and this complex is also referred to as the small latent complex (SLC). LAP can be covalently associated with latent TGF-beta binding proteins (LTBP) through disulfide bonds, forming the large latent complex (LLC). The association of LAP with TGF-beta facilitates its secretion and also renders TGF-beta inactive.

- Figure 3. Affect of ECR3E on alpha V beta 6 -mediated latent TGF-beta activation and LLC formation. CHO/beta 6 cells were transduced with empty, ECR3E- or ECR4E-expressing viruses. (A) The transduced cells were co-cultured with TGF-beta-reporter TMLCs for 16-24 h before harvesting cell lysates and measuring luciferase activity. Experiments were performed in triplicate and the SDs of a single experiment are given. The errors bars represent the SD of a single experiment that was performed in triplicate. This experiment was repeated multiple times with similar results. (B) The transduced cells were transiently transfected with a TGF-beta1 cDNA expression vector and allowed to generate CM for 16-24 h. The media were used for Western blotting. The reactive bands were revealed with an anti-LAP antibody (Vb3A9).
