Flow cytometry (Routinely Tested)
0.5 mg/ml
Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. 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 11-5.2 monoclonal antibody specifically recognizes the α chain of the I-A[k] MHC class II alloantigen. It cross-reacts with cells from mice of the H-2[r] haplotype. mAb 11-5.2 recognizes the Ia.19 determinant, and it's reactivity is dependent upon the presence of Glu at position 75 of the Aα chain. Reactivity with other H-2 haplotypes (e.g., b, d, f, p, q, s) has not been observed.

Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
