Description
The 194128 monoclonal antibody specifically binds to Siglec-5 (Sialic acid binding Ig-like lectin 5) and Siglec-14 (Sialic acid-binding Ig-like lectin 14). Siglec-5 is also known as CD170, CD33 antigen-like 2 (CD33L2) and OBBP2 (OB binding protein-2) whereas Siglec-14 is also referred to as SIG14. Both molecules are type I transmembrane glycoproteins that belong to the SIGLEC (sialic acid binding Ig-like lectin) family within the immunoglobulin superfamily. Siglec-5 can bind to alpha-2, 3- and alpha-2, 6-linked sialic acid glycoproteins and glycolipids. It is highly expressed on neutrophils and expressed at lower levels by monocytes/macrophages and dendritic cells. Siglec-5 can function as an inhibitory receptor for some cellular responses and enhance the anti-phagocytic responses by some macrophages. Siglec-14 has 99.5% amino acid sequence homology with Siglec-5 within their first two extracellular Ig domains and has a similar ligand binding preference. Siglec-14 is expressed by cells of myeloid origin and serves as an activating receptor.
The antibody was conjugated to BD Horizon BB515 which was developed exclusively by BD Biosciences. With an excitation max of 490 nm and an emission max of 515 nm, BD Horizon BB515 can be excited by the 488 nm laser and detected in a standard FITC set (eg, 530/30-nm filter). This dye provides a much brighter alternative to FITC with less spillover into the PE detector.
Format
BB515 is a dye that was exclusively developed by BD Biosciences as a brighter alternative to FITC. This dye is up to seven times brighter than FITC and has less spillover into the PE channel. Due to similar excitation and emission properties, BB515, FITC, and Alexa Fluor® 488 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with BD Horizon™ BB515 under optimum conditions and unconjugated antibody was removed.
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- The manufacture, use, sale, offer for sale, or import of this product is subject to one or more patents or pending applications. This product, and only in the amount purchased by buyer, may be used solely for buyer’s own internal research, in a manner consistent with the accompanying product literature. No other right to use, sell or otherwise transfer (a) this product, or (b) its components is hereby granted expressly, by implication or by estoppel. Diagnostic uses require a separate license.

- Please refer to www.bdbiosciences.com/pharmingen/protocols for technical protocols.
For optimal results, it is recommended to perform 2 washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescent staining, prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.
