What is K562 cell line?
What is K562 cell line?
Cell Line Description K562 cells were established the first human immortalized myelogenous leukemia line. This cell line is derived from a 53-year-old female chronic myelogenous leukemia patient in blast crisis. They can be used as a highly sensitive target for the in vitro natural killer assay.
How do you thaw a K562 cell?
Thaw cells directly from cryo in 37oC water bath, swirl tube until only small bit of ice still visible, then transfer cells directly into 1/2 volume (5mL) warm media. Use remaining 1/2 dilution volume (5mL) media to rinse cryo vial.
Do K562 cells express CD19?
The negative control cell line, K562, does not express CD22 or CD19. We next evaluated blasts from 110 patients with BCP-ALL by flow cytometry.
What cells are K562?
K562 cells were the first human immortalised myelogenous leukemia cell line to be established. K562 cells are of the erythroleukemia type, and the cell line is derived from a 53-year-old female chronic myelogenous leukemia patient in blast crisis.
How fast do K562 cells grow?
K562 cells usually take 3 days or more to recover from freezing. 1. These cells reach log phase in 5-‐7 days. Start counting at day 3.
What are 293T cells?
The 293T cell line, originally referred as 293tsA1609neo, is a highly transfectable derivative of human embryonic kidney 293 cells, and contains the SV40 T-antigen. Age fetus Comments. This cell line is competent to replicate vectors carrying the SV40 region of replication.
How do I choose a cell line?
The Do’s and Dont’s of Choosing a Cell Line
- Don’t Choose Simply Because It Is Used in the Literature.
- Do Consider If It Fits Your Biological Model.
- Do Consider the Experiments You Want to Perform.
- Table 1: Features of commonly used cell lines.
- Don’t Assume That All Cell Lines Have the Same Culturing Requirements.
What can K562 cell lines be used for?
The paired K562-s and K562-r clones are useful cell line models of sensitivity and resistance to a tyrosine kinase inhibitor used in the treatment of chronic myeloid leukemia. Price from $9.99 to $1999.99 Figure Legend Snippet: ENCODE ChIP-seq datasets display internal inconsistency and incongruity.
What kind of cells are K-562 blasts?
K-562 blasts are multipotential, hematopoietic malignant cells that spontaneously differentiate into recognizable progenitors of the erythrocytic, granulocytic and monocytic series. The effect of inducers on sublines derived from the original K-562 cell line have been reviewed by Koeffler and Golde.
How are CHO cells co-transfected with K562 cells?
Cells were co-transfected (nucleofection of Jurkat and K562 cells and lipofection of CHO cells) with expression plasmids for the indicated receptors and IRES plasmids encoding Nef and GFP or a null Nef mutant and GFP (vector).
Can a K562 cell line express a null mutant?
K562 cells were nucleofected with wt or WM CXCR4 and a bicistronic IRES plasmid encoding wt Nef or a null mutant and GFP. Data for Nef (−) GFP (+) and Nef (+) GFP (+) K562 cells expressing wt (top) or WM CXCR4 (bottom) were separately analyzed.
