Description
The RL388 monoclonal antibody recognizes CD98 which is also known as the 4F2 antigen and Ly-10. CD98 is a disulfide-linked heterodimer comprised of an ~86 kDa single-pass type II heavy chain glycoprotein that associates with a ~39-kDa multi-pass, nonglycosylated light chain which belongs to the L-type amino transporter family. The RL388 antibody specifically binds to an epitope present on the CD98 heavy chain (CD98hc, also known as the 4F2 cell-surface antigen heavy chain or 4F2hc) which is encoded by Slc3a2 [solute carrier family 3 (activators of dibasic and neutral amino acid transport), member 2]. CD98 is variably expressed on different cell types including T cells, B cells, and NK cells as well as monocytes, granulocytes, platelets, and fibroblasts. CD98 serves as an activation marker for T and B cells since its expression is upregulated upon cellular activation. CD98 regulates cellular growth, proliferation, and survival through CD98hc interactions with β integrins and by CD98 light chain-mediated amino acid transport.
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® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
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.

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.
5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. 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.
7. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

9. An isotype control should be used at the same concentration as the antibody of interest.
