Latent TGF-β is secreted as a complex consisting of LAP and TGF-β1. LAP and TGF-β1 are synthesized as a single propeptide precursor of 390 amino acids with an N-terminal signal peptide of 29 amino acids, a 249 amino acids pro-region (LAP), and a 112 amino acids C-terminal region (TGF-β1).
Both LAP and TGF-β1 exist as homodimers in circulation, but the disulfide linked homodimers of LAP and TGF-β1 remain non-covalently associated, forming the small latent TGF-β complex (SLC, 100 kD). The large latent TGF-β complex (LLC, 235-260 kD) contains a third component, the latent TGF-β binding protein (LTBP), which is linked to LAP by a single disulfide bond. LTBP does not confer latency but is for efficient secretion of the complex to extracellular sites.
TGF-β1 and LAP can be released (activated) by many factors, including enzymes and low or high pH. TGF-β1 and LAP have multiple functions, such as regulating proliferation and differentiation of various cell types.
Increased production and activation of latent TGF-β have been linked to immune defects associated with malignancy and autoimmune disorders, susceptibility to opportunistic infection, and to the fibrotic complications associated with chronic inflammatory conditions.
Latent TGF-β has been found to protect against glomerulonephritis. It is also a surface marker of activated regulatory T cells.

- Recommended Usage
-
Concentrations of 1 µg/mL and 0.5 µg/mL of the capture antibody were utilized to generate the example standard curves for human latent TGF-β and mouse latent TGF-β, respectively. It is recommended that each lot of reagent be titrated for optimal performance for each application.
- Application Notes
-
ELISA Capture:
To measure human latent TGF-ß, this antibody can be used as a capture antibody in sandwich ELISA format, and paired with the biotinylated TW4-6H10 antibody (Cat. No. 349707) as the detection antibody. Recombinant human latent TGF-ß (ELISA Std.) (Cat. No. 593509) can be used as the protein standard.
To measure mouse latent TGF-ß, this antibody can be used as a capture antibody in sandwich ELISA format, and paired with the biotinylated TW7-16B4 antibody (Cat. No. 141411) as the detection antibody. Recombinant mouse latent TGF-ß (ELISA Std.) (Cat. No. 594509) can be used as the protein standard.
Note: For testing human latent TGF-ß in serum, plasma or supernatant, LEGEND MAX™ Human Latent TGF-ß ELISA Kit (Cat. No. 432907) is specially developed and recommended. For testing mouse latent TGF-ß, LEGEND MAX™ Mouse Latent TGF-ß ELISA Kit (Cat. No. 433007) is recommended. - Product Citations

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
