Initial Handling Guidelines	1. Thaw the vial in 37ºC water bath approximately 1-2 minutes. 2. Transfer the cell suspension to a 15 ml/50 ml conical sterile polypropylene centrifuge tube containing pre-warmed culture medium. Wash vial with an additional culture medium to collect remaining cells, and centrifuge at 201 × g (rcf) for 5 minutes at room temperature. 3. Resuspend the cell pellet in 5 ml pre-warmed culture medium and count cell number. Seed cells in an appropriate cell culture flask at a density of 2×10⁴ cells/cm². This should allow for confluency within 48 hours. 4. Incubate the culture at 37ºC incubator with 5% CO₂. Cultures should be monitored daily.
Subculture Guidelines	Cells should be passaged when they have achieved 80-90% confluence. A partial media change 24 hours prior to subculture may be helpful to encourage growth.
Description	Human wild-type HEK293T cell line as the recommended control.

Tissue Specificity	Most isoforms are expressed in many tissues, including brain, heart, liver, and skeletal muscle. Isoform 2 is only found in the heart and skeletal muscle. Isoform 14 is only found in the brain.
Target Sequence Similarities	Belongs to the AGC Ser/Thr protein kinase family, DMPK subfamily.
