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 to the dye under optimum conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD CompBead to ensure that BD CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Researchers should determine the optimal concentration of this reagent for their individual applications.
  2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. 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.

371805

The 371805 monoclonal antibody specifically recognizes Ephrin type-A receptor 2 (EphA2).  EphA2 is a ~130 kDa type I transmembrane glycoprotein that is encoded by EPHA2 (EPH receptor A2) which belongs to ephrin receptor subfamily within the receptor tyrosine kinase (RTK) family. EphA2 is also known as Epithelial cell kinase (ECK) or Epithelial cell receptor protein tyrosine kinase. The extracellular region of EphA2 contains an N-terminal globular domain, a cysteine-rich domain and 2 fibronectin type III repeats, whereas the cytoplasmic domain contains two tyrosine residues adjacent to the membrane that function as major autophosphorylation sites and a kinase domain. EphA2 is variably expressed by epithelial cells, dendritic cells, Langerhans cells, keratinocytes, and endothelial cells. EphA2 functions as a receptor for glycophosphatidylinositol (GPI) membrane-linked members of the Ephrin-A family, including Ephrins A1-A5. EphA2 is involved in regulating cellular growth, adhesion, migration, survival, and plays a role in angiogenesis. Its expression may be upregulated on vascular endothelium in certain breast, prostate, and colon cancers as well as on some metastatic tumor cells.

The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.

R718
The BD Horizon™ Red 718 (R718) Dye is part of the BD red family of dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 695-nm and an emission maximum (Em Max) at 718-nm. Driven by BD innovation, R718 is designed to be excited by the red laser (627–640-nm) and detected using an optical filter centered near 720-nm (e.g., a 720/40-nm bandpass filter). R718 is a brighter alternative to Alexa Fluor™ 700. R718 is also a bright small molecule alternative to APC-R700 with lower spread into the APC detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
