Obtaining high-quality single-cell suspensions efficiently in a short time is a prerequisite for many subsequent cell-related experiments. This kit utilizes a specially optimized dissociation enzyme formulation to rapidly dissociate small kidney tissue into high-quality kidney tissue single-cell suspensions. The obtained single-cell suspensions can be used for subsequent single-cell sequencing, cell culture, flow cytometry, and other cell-related experiments. [In most cases, 100mg of tissue lyses in 5-8 minutes, yielding 3-4.5 million cells with approximately 90% viability after red blood cell lysis.]
