Human CD34 Cell Enrichment Kit (Negative Selection) is commonly used in hematology and stem cell research Originating from the need to isolate hematopoietic stem and progenitor cells this kit targets specific cell surface markers to enable the negative selection of CD34 cells The mechanism involves the depletion of unwanted cells allowing the enrichment of CD34 cells without direct labeling preserving their native state In vitro this method allows for effective cell separation typically within the nanomolar to low micromolar range of activity It is widely utilized in various applications including cell culture models animal studies and drug screening providing a purified population of stem cells for downstream experiments Experimental concentrations typically depend on the specific research design The kit facilitates advancements in regenerative medicine by aiding the study of stem cell behavior and potential therapeutic applications
