General description
Latent-transforming growth factor beta-binding protein 4 (UniProt: Q8N2S1; also known as LTBP-4) is encoded by the LTBP4 gene (Gene ID: 8425) in human. LTBP4 is a key regulator of transforming growth factor β that controls TGF-β activation by maintaining it in a latent state during storage in extracellular space. It associates specifically via disulfide bonds with the latency-associated peptide (LAP), which is the regulatory chain of TGF-β. It is highly expressed in heart, skeletal muscle, pancreas, uterus, and small intestine. In human a long form (LTBP4-L) and a short isoform (LTBP4-S) have been described. LTBP4-L exhibits higher affinity for TGF-β1 compared to LTBP4-S form. Mice deficient in LTBP4-S form exhibit pulmonary emphysema, colorectal cancer, and cardiomyopathy. LTBP4 is reported to be upregulated in patients with chronic kidney disease and fibrotic mice kidneys. Down-regulation of LTBP4 expression is identified in melanoma tissues and cells and is associated with poor prognosis. Inhibition of LTBP4 is shown to reduce apoptosis and promote cell proliferation and metastasis. Four isoforms of LTBP4 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonal.

ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.
Immunogen
KLH-conjugated linear peptide corresponding to 25 amino acids from the N-terminal half of human Latent-transforming growth factor β-binding protein 4 (LTBP4).
Application
Quality Control Testing
Evaluated by Western Blotting in EL4 cell lysate.
Western Blotting Analysis: A 1:1.000 dilution of this antibody detected LTBP4 in EL4 cell lysate.
Tested Applications
Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected LTBP4 in Human kidney and Human epididymis tissue sections.
Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected LTBP4 in HepG2 and K562 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Biochem/physiol Actions
Clone 2M8 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Latent-transforming growth factor β-binding protein 4 (LTBP4). It targets an epitope within 25 amino acids from the N-terminal half.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
