Human LAP (TGF-beta 1) Antibody Summary
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
LAP (TGF-beta 1) in HEK293 Human Cell Line. LAP (TGF-beta 1) was detected in immersion fixed HEK293 human embryonic kidney cell line using Mouse Anti-Human LAP (TGF-beta 1) Monoclonal Antibody (Catalog # MAB246) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 493-conjugated Anti-Mouse IgG Secondary Antibody (green; Catalog # NL009) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
LAP TGF‑ beta 1 Inhibition of TGF‑ beta 1 Activity and Neutralization by Human LAP TGF‑ beta 1 Antibody. Recombinant Human LAP TGF‑ beta 1 (Catalog # 246-LP) inhibits Recombinant Human TGF‑ beta 1 (Catalog # 240-B) growth inhibition activity in the HT‑2 mouse T cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human TGF‑ beta 1 (1 ng/mL) activity elicited by Recombinant Human LAP TGF‑ beta 1 (500 ng/mL) is neutralized (green line) by increasing concentrations of Human LAP TGF‑ beta 1 Monoclonal Antibody (Catalog # MAB246). The ND50 is typically 1-5 µg/mL.

Background: LAP (TGF-beta 1)
The TGF-beta family includes several related proteins (70-80% sequence homology) from mammalian, avian, or Xenopus systems that are now designated TGF-beta 1, TGF‑ beta 2, TGF-beta 1.2, TGF-beta 3, TGF-beta 4, and TGF-beta 5. These proteins are secreted by cells in the form of an inactive complex, referred to as latent TGF-beta, that consists of TGF-beta associated non-covalently with a Latency-associated peptide (LAP). These two proteins are synthesized as a single pro-peptide that is cleaved in a post Golgi compartment prior to secretion. Different TGF-beta family members are naturally associated with their own distinct LAPs.
