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.

特異性

Clone 1O8 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Sialic acid-binding immunoglobulin-like lectin 1 (Siglec1/CD169). It targets an epitope within 21 amino acids from the internal region.

免疫原

KLH-conjugated linear peptide corresponding to 21 amino acids from the internal region of human Sialic acid-binding immunoglobulin-like lectin 1 (Siglec1/CD169).

標靶描述

Sialoadhesin (UniProt Q9BZZ2; also known as CD169, Sialic acid-binding Ig-like lectin 1, Sialic acid-binding immunoglobulin-like lectin 1, Siglec-1) is encoded by the SIGLEC1 (also known as SN) gene (Gene ID 6614) in human. Sialoadhesin/CD169/Siglec1 is the founding member of the sialic acid-binding immunoglobulin lectins (Siglec) expressed on a variety of leukocytes and stromal cells. Siglec1 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off to produce the mature for that contains a large extracellular domain (aa 20-1641), a transmembrane domain (aa 1642-1662), and a short cytoplasmic domain (aa 1663-1709) with no known signal transduction or endocytosis motifs. The extracellular portion contains an N-terminal Ig-like V-type domain (aa 20-136), followed by sixteen Ig-like C2-type domains. Siglec1 is highly expressed on the subcapsular sinus (SCS) and medullary macrophages in lymph node (LN) and on marginal metallophilic macrophages in the marginal zone (MZ) of spleen. Although sialic acids are found on the surface of all cells and most secreted proteins, only heavily sialylated, multimeric structures are captured by Siglec1 on macrophages via its N-terminal Ig-like V-type domain due to a low (millimolar) Affinity^™ toward sialylic acid. Siglec1-mediated sialic-acid recognition allows macrophages to engage sialylated pathogens and stimulate inflammatory responses. Siglec1 is also reported to capture of B cell-derived exosomes via their surface-expressed α2, 3-linked sialic acids. In the lymph node, exosomes are not retained in the subcapsular sinus of Siglec1-knockout mice and penetrate deeper into the paracortex, causing an enhanced response to antigen-pulsed exosomes among Siglec1-/- mice. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

外觀

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

重構

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

儲存和穩定性

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.
