Applications

Recommended Concentration
Sample
ELISA

This antibody functions as an ELISA capture antibody when paired with Mouse Anti-Human LAP (TGF-beta 1) Monoclonal Antibody (Catalog # MAB7754).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human LAP (TGF-beta 1) DuoSet ELISA Kit (Catalog # DY246) for convenient development of a sandwich ELISA or the Human LAP (TGF-beta 1) Quantikine ELISA Kit (Catalog # DLAP00) for a complete optimized ELISA.

 
CyTOF-ready
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Intracellular Staining by Flow Cytometry Detection of LAP (TGF-beta 1) antibody in PC-3 human prostate cancer cell line antibody by Flow Cytometry. View Larger

Detection of LAP (TGF‑ beta 1) in PC‑3 human prostate cancer cell line by Flow Cytometry. PC-3 human prostate cancer cell line was stained with Mouse Anti-Human LAP (TGF-beta 1) Monoclonal Antibody (Catalog # MAB77541, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram) followed by APC-conjugated anti-Mouse IgG secondary antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3/Transcription Factor Fixation & Perm Buffer Kit (Catalog # FC012).

LAP (TGF‑ beta 1) in K562 Human Cell Line. LAP (TGF-beta 1) was detected in immersion fixed K562 human chronic myelogenous leukemia cell line using Mouse Anti-Human LAP (TGF-beta 1) Monoclonal Antibody (Catalog # MAB77541) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

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 # MAB77541) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Human LAP (TGF‑ beta 1) ELISA Standard Curve. Recombinant Human LAP (TGF-beta 1) protein was serially diluted 2-fold and captured by Mouse Anti-Human LAP (TGF-beta 1) Monoclonal Antibody (Catalog # MAB77541) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human LAP (TGF-beta 1) Monoclonal Antibody (Catalog # MAB7754) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: LAP (TGF-beta 1)

TGF-beta 1, -2, and -3 are a closely related group of proteins (70-80% sequence homology) that are produced by many cell types and function as growth and differentiation factors. The active forms of TGF-beta 1, -2, and -3 are disulfide-linked homodimers.
