Sigma Hematology Retic Stain - 120 mL

The Sigma Hematology Retic Stain is a ready-to-use 120 mL solution specifically formulated for staining reticulocytes in peripheral blood samples. Reticulocyte counts are a key diagnostic metric in hematology, providing insight into bone marrow erythropoietic activity and helping clinicians assess conditions such as anemia, monitor response to therapy, and evaluate bone marrow recovery following chemotherapy or transplantation. This stain highlights the residual ribosomal RNA network within immature red blood cells, making them distinguishable from mature erythrocytes under microscopic examination.

As a Sigma-branded laboratory reagent, this stain is manufactured under controlled quality standards to deliver batch-to-batch consistency — a critical factor when reticulocyte counts must be accurate and reproducible across multiple tests and time points. The ready-to-use format eliminates the variability and time associated with manual preparation, allowing lab technicians to proceed directly to the staining protocol. The 120 mL volume is well-suited for clinical laboratories with moderate sample throughput, providing enough reagent for numerous procedures while maintaining a manageable shelf footprint.
