Detects human LYVE-1 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 35% cross-reactivity with recombinant mouse LYVE-1 and less than 1% cross-reactivity with recombinant human CD44 is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human LYVE-1 Ser24-Thr238 Accession # Q9Y5Y7
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.30 EU per 1 μg of the antibody by the LAL method.
Blockade of Receptor-ligand Interaction
In a functional ELISA, 0.4 - 2 µg/mL of this antibody will block 50% of the binding of 250 ng/mL of biotinylated Hyaluronan to immobilized Recombinant Human LYVE-1 (Catalog # 2089-LY) coated at 5 µg/mL (100 µL/well). At 20 μg/mL, this antibody will block >90% of the binding.
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.
LYVE‑1 in Human Tonsil. LYVE‑1 was detected in immersion fixed paraffin-embedded sections of human tonsil using 15 µg/mL Goat Anti-Human LYVE‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2089) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human LYVE‑1 by Western Blot. Western blot shows lysates of human liver and spleen tissue. PVDF membrane was probed with 0.25-1 µg/mL of Goat Anti-Human LYVE‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2089) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for LYVE‑1 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Lymphatic vessel endothelial hyaluronan (HA) receptor-1 (LYVE-1) is a receptor of HA, a linear high molecular weight polymer composed of alternating units of D‑glucuronic acid and N-acetyl-D-glucosamine. HA is found in the extracellular matrix of most animal tissues and in body fluids. It modulates cell behavior and functions during tissue remodeling, development, homeostasis, and disease (1). The turnover of HA (several grams/day in humans) occurs primarily in the lymphatics and liver, the two major clearance systems that catabolize approximately 85% and 15% of HA, respectively (1-3). LYVE-1 shares 41% homology with the other known HA receptor, CD44 (4). The homology between the two proteins increases to 61% within the HA binding domain. The HA binding domain, known as the link module, is a common structural motif found in other HA binding proteins such as link protein, aggrecan and versican (1, 5). Human and mouse LYVE-1 share 69% amino acid sequence identity.
LYVE-1 is primarily expressed on both the luminal and abluminal surfaces of lymphatic vessels (4, 5). In addition, LYVE-1 is also present in normal hepatic blood sinusoidal endothelial cells (6). LYVE-1 mediates the endocytosis of HA and may transport HA from tissue to lymph by transcytosis, delivering HA to lymphatic capillaries for removal and degradation in the regional lymph nodes (5, 7, 8). Because of its restricted expression patterns, LYVE-1, along with other lymphatic proteins such as VEGF R3, podoplanin and the homeobox protein propero-related (Prox-1), constitute a set of markers useful for distinguishing between lymphatic and blood microvasculature (4, 5, 9-11).
