Hap1 c631 cells

Manufactured by Horizon Discovery

HAP1 C631 cells are a population of haploid human cell lines derived from the chronic myelogenous leukemia (CML) cell line KBM-7. These cells contain a single copy of each chromosome and are commonly used for genetic studies and loss-of-function screening.

Generating Stable Cas9-Expressing HAP1 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Wild-type HAP1 C631 cells were ordered from Horizon Discovery and maintained at 37 °C, 5% CO2 in IMDM (Life Technologies) supplemented with 10% FCS. For stable Cas9 expression, the parental cell line was transduced at an MOI of ~ 0.5 with lentivirus generated using the Lenti Cas9-2A-Blast plasmid (kind gift of the Moffat lab, Addgene #73310) and selected with 20 μg/ml blasticidin (InvivoGen) for at least 1 week. Out of this bulk population, single cells with a small cell size (indicative for a haploid genotype) were sorted in 96-well plates, expanded, and again selected with 20 μg/ml blasticidin. blasticidin-resistant clones were further characterized for Cas9 editing efficiency. Mycoplasma contamination was periodically assessed for all cell lines. The HAP1 cell line was authenticated using Multiplex Cell Authentication by Multiplexion (Heidelberg, Germany) as described recently [68 (link)]. The SNP profile was unique.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
