Control the Quality of Your Flow

Commercially available Quality Control materials bring third party verification to analytical and diagnostic procedures. This is an increasingly important requirement for laboratories working towards or maintaining ISO 15189 accreditation. Flow cytometry systems, such as those from BD Biosciences and Beckman Coulter®, are well supported with a wide range of specialty control materials from Streck, supplied in the UK by Alpha Laboratories.

The latest addition to this range is CD-Chex TdT™ Plus. This quality control material enables evaluation of intracellular and surface antigens with assigned values for CD1a, CD2, CD4, CD5, CD7, CD8, CD34 cytoplasmic CD3, and nuclear TdT (Terminal deoxynucleotidyl Transferase) when stained with fluorescent antibodies and analysed by flow cytometry. These CD markers provide valuable information on the presence of the abnormal cells often found in certain types of hematopoietic neoplasms.

Like all Streck CD-Chex products, CD-Chex TdT™ Plus quality control material has excellent shelf-life characteristics, with 90 day closed vial stability (from the date of manufacture) and 30 day open vial stability.
