Description
The Alemtuzumab297.rMAb (also known as, Alemtuzumab N297A Biosimilar.rMAb) is a research grade humanized recombinant human IgG1, kappa antibody that specifically recognizes the extracellular domain of human CD52, similarly to the therapeutic Alemtuzumab antibody. The Alemtuzumab297.rMAb uses variable region sequences from Alemtuzumab and constant region consensus sequences from human IgG1 kappa. The asparagine at position 297 of the constant heavy chain has been replaced with alanine (N297A) to further reduce Fc receptor interactions. The CD52 antigen is a 25-29 kDa N-glycosylated, GPI-linked protein that is also known as Cambridge pathology antigen 1 (CAMPATH-1 antigen), or Human epididymis-specific protein 5 (He5). It is expressed on thymocytes, lymphocytes, monocytes, macrophages, dendritic cells, and eosinophils, but is weakly or not expressed on neutrophils, erythrocytes, platelets, or hematopoietic stem cells. CD52 is variably expressed on malignant lymphoid cells and serves as a target for therapeutic CD52-specific antibodies. The Alemtuzumab297.rMAb is intended for research use only. It is not intended for use in therapeutic or diagnostic procedures for humans or animals.
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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
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. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).

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