title: GSM8010562: AML336 Control scRNA Seq; Homo sapiens; RNA-Seq
library_construction_protocol: Frozen patient derived AML BM cells stored in liquid nitrogen were retrieved right before sample processing. To maximize the cellular viability recovery, samples were processed in batches according to thawing protocol. Briefly, cells were gently thawed in water bath at 37 °C for 2 minutes until partially thawed and immediately transferred to a 50 mL conical tube with 1ml of prewarmed media (RPMI1640 supplemented with 10% FBS) and centrifuged (300 g for 5 min). Cells were sequentially diluted 1:1 3 times with prewarmed RPMI containing 10% FBS. Cells were centrifuged at 300 x g for 5 minutes in a swinging bucket centrifuge. After finishing centrifugation, supernatant was disposed, the cell pellet was carefully re-suspended in 1 mL of 2% FBS/PBS, centrifuged at 300 x g for 5 minutes and resuspended in 900 uL of 2% FBS/PBS. To removed dead cells and debris, cells were passed through a 40 micron Flow-mi strainer and the cell concentration of the concentrated cell stock was determined with a Countess counting device.  The desired number of targeted cells (5000-10,000) from the concentrated cell stock were separated on the 10X Chromium Controller. scRNA Seq libraries were constructed following the 10X Genomics protocol for single cell RNA Seq analysis.
