The Human embryonic kidney 293 cells, commonly known as HEK 293, HEK-293, or simply 293 cells, represent an endlessly dividing cell line that originates from HEK cells originally extracted from a female fetus in the decade of the 1970s.
MCF-7, an acronym representing Michigan Cancer Foundation-7, is a breast cancer cell line that was originally isolated in 1970 from a Caucasian female patient aged 69. This cell line was established in 1973 at the Detroit-based institute by Herbert Soule and his colleagues.
(Rapid thawing process)
To initiate the thawing process efficiently, take the HEK293T packaging cell line out of liquid nitrogen and submerge it in a 37 ºC water bath for approximately 2 minutes, or until it has reached a thawed state of roughly 80%. Subsequently, gently extract the cells from the vial and carefully dispense them into a 15 mL conical tube that is already containing 10 mL of pre-warmed Hyclone HEK293T Culture Medium.
CD4-expressing T lymphocytes, commonly referred to as helper T cells, are highly recognized for their remarkable ability to produce cytokines. This specific subset can be further categorized into Th1 and Th2 cells, with the cytokines they secrete being designated as Th1-type cytokines and Th2-type cytokines respectively.rec-1 cell line
The HT1080 (ATCC® CCL-121™) cell line originates from a fibrosarcoma in a 35-year-old Caucasian male.
The PC12 cell line stands as a frequently employed tool in neuroscience research, encompassing investigations pertaining to neurotoxicity, neuroprotection, neurosecretion, neuroinflammation, as well as synaptogenesis. mda-mb-453 doubling time
Especially for U87MG cells, it is anticipated that their population doubling time would be around 34 hours, as stated in their product specifications (ATCC HTB-14, United States).
The 293 Cell Line is a stable cell line derived from primary human embryonal kidney cells that have been genetically modified using fragmented human adenovirus type 5 DNA (Graham et al., 1977; Harrison et al., 1977). This line serves as a parental cell line for various experimental purposes.
The HT1080 (ATCC® CCL-121™) cell line originates from a human fibrosarcoma tissue sample taken from a 35-year-old Caucasian male. These cells exhibit an adhesive nature and display an epithelial-like morphological structure. Upon transplantation into immunocompromised mice, these cells have the ability to develop into primary tumors and generate distant metastases.
By incorporating the Ad5 E1A and E1B genes into the HEK genome, the cell line achieved immortality by disrupting cell cycle regulation and suppressing apoptosis, respectively. Furthermore, the existence of Ad5 facilitated the production of recombinant proteins in high quantities, particularly proteins encoded within plasmid vectors harboring the CMV promoter.huo9
