Product Details

Brand: BD OptiBuild™

Alternative Name: KEL; KELL; Kell blood group, metallo-endopeptidase; ECE3

Reactivity: Human (Tested in Development)

Isotype: Mouse IgG1, κ

Immunogen: Human erythrocytes

Application: Flow cytometry (Qualified)

Concentration: 0.2 mg/ml

Workshop Number: VII 70565

RRID: AB_2740959

Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.

Regulatory Status: RUO

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 BV421 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).

Product Notices

This antibody was developed for use in flow cytometry.
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.
Researchers should determine the optimal concentration of this reagent for their individual applications.
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.

Antibody Details

BRIC 203

The BRIC 203 monoclonal antibody specifically binds to the Kell blood group antigen, Kp(a-b+) but not Kp(a+b-), also known as the Kell blood group metallo-endopeptidase, KELL, ECE3 and CD238. CD238 is an approximately 115-kDa type II transmembrane glycoprotein that is encoded by the KEL gene. CD238 functions as a zinc endopeptidase that cleaves endothelin-3 into an active form which can function as a vasoconstrictor. CD238 is expressed on erythrocytes, human embryonic stem cell-derived endoderm and on cells from various other tissues, including testis, heart, brain and skeletal muscle. Decreased expression of CD238 is associated with the McLeod phenotype as a consequence of losing XK protein expression. Kell antigen expression can play an important role during blood transfusions and also specific autoimmune diseases related to Kell antigen recognition. During development the BRIC 203 monoclonal antibody was found to detect the CD238 antigen by flow cytometric analysis of human erythrocytes. It reportedly works in immunoprecipitation and agglutination assays.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

Format Details

BV421

The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
