Regulatory Status Legend
The YLI-90 monoclonal antibody specifically reacts with the B6 alloantigen of Ly-49I, an inhibitory receptor which is expressed on subsets of natural killer (NK) cells, NK-1.1+ (or DX5+) T lymphocytes (NK-T cells), and on a population of memory CD8+ T lymphocytes in C57BL/6 mice, but not AKR/J, BALB/c, DBA/1, or SJL mice. The Ly-49 family of NK-cell receptors are disulfide-linked type-II transmembrane protein homodimers with extracellular carbohydrate-recognition domains (CRD). Ly-49I is closely related to Ly-49C[B6] and Ly49C[BALB], and these three alloantigens are recognized by mAb 5E6 (Cat. No. 553277). A Ly-49I[BALB] allele has not been found. The Ly-49 family members are expressed independently, such that an individual NK or T cell may display more than one class of Ly-49 receptor homodimers. Binding of Ly-49I-expressing transfectants to cell lines bearing MHC class I antigens of the b,d, k and s haplotypes was not detected. In contrast, Ly-49I-expressing transfectants were found to weakly bind lymphoblasts of the b, d, k, q, s, and v haplotypes and to strongly bind H-2[r] lymphoblasts. Ly-49I-bearing NK cells may mediate allogeneic and hybrid resistance to transplantation of H-2[d] bone marrow.

R-phycoerythrin (PE) is an accessory photosynthetic pigment found in red algae. It exists in vitro as a 240-kDa protein with 23 phycoerythrobilin chromophores per molecule. This makes PE one of the brightest fluorochromes for flow cytometry applications, but its photobleaching properties make it unsuitable for fluorescence microscopy.

Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- 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.
