Invitrogen is one of several brands under the Thermo Fisher Scientific corporation. The product line includes various subbrands of biotechnology products, such as machines and consumables for polymerase chain reaction, reverse transcription, cloning, culturing, stem cell production, cell therapy, regenerative medicine, immunotherapy, transfection, DNA/RNA purification, diagnostic tests ...
Tissue culture flasks. RPMI 1640, simply known as RPMI medium, is a cell culture medium commonly used to culture mammalian cells. [1] RPMI 1640 was developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at Roswell Park Comprehensive Cancer Center (formerly known as Roswell Park Memorial Institute), from where it derives its name. [2]
High Five (BTI-Tn-5B1-4) is an insect cell line that originated from the eggs of the cabbage looper, Trichoplusia ni. [1] It was developed by the Boyce Thompson Institute for Plant Research.
Life Technologies was originally formed in 2008 through a $6.7B merger of Invitrogen, a cell therapy, and Applied Biosystems. [29] The company also acquired GIBCO (Grand Island Biological Company) as part of the Life Technologies acquisition. [30]
Cells which have been successfully transformed with pUC19 can be differentiated from cells which have not by growing them on media with ampicillin. Only the cells with the plasmid containing amp R will survive. The origin of replication (ori), is derived from the plasmid pMB1. [6] [1] pUC19 is a high copy number plasmid. [3]
Mediating RNA interference in cultured mammalian cells. Small interfering RNA ( siRNA ), sometimes known as short interfering RNA or silencing RNA , is a class of double-stranded non-coding RNA molecules , typically 20–24 base pairs in length, similar to microRNA (miRNA), and operating within the RNA interference (RNAi) pathway.
Vectors are transfected into the cells and the DNA may be integrated into the genome by homologous recombination in the case of stable transfection, or the cells may be transiently transfected. Examples of mammalian expression vectors include the adenoviral vectors, [ 38 ] the pSV and the pCMV series of plasmid vectors, vaccinia and retroviral ...
For example, the identity of proteins of the immune system (e.g. antibodies), and the mechanism by which they recognize and bind to foreign antigens would remain very obscure if not for the extensive use of in vitro work to isolate the proteins, identify the cells and genes that produce them, study the physical properties of their interaction ...
