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.
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. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. 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.
2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
3. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
4. An isotype control should be used at the same concentration as the antibody of interest.
5. 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.

7. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.
