Sf9 (cells) - Wikipedi

Sf9 cells, a clonal isolate of Spodoptera frugiperda Sf21 cells (IPLB-Sf21-AE), are commonly used in insect cell culture for recombinant protein production using baculovirus. They were originally established from ovarian tissue. They can be grown in the absence of serum, and can be cultured attached or in suspension Sf-9-Zellen in serumfreien Medium Sf-9 ist eine immortalisierte Insekten - Zelllinie aus Ovar - Zellen von Spodoptera frugiperda, einer Nachtfalterart, die zur Familie der Eulenfalter (Noctuidae) und zur Ordnung der Schmetterlinge (Lepidoptera) zählt. Diese wird in der Biotechnologie zur Produktion von rekombinanten Proteinen verwendet The Sf9 insect cell line is a clonal isolate derived from the parental Spodoptera frugiperda cell line IPLB-Sf-21-AE, and it is a suitable host for expression of recombinant proteins from baculovirus expression systems (e.g., Invitrogen's Bac-to-Bac® and Bac-N-Blue™ Expression Systems) Sf9 cells are a clonal isolate from Spodoptera frugiperda (Fall armyworm) IPLB-Sf21-AE cells. The Sf9 cells are adapted to serum free suspension culture in ESF 921™ media but are capable of conforming to other suitable media types Gibco® Sf9 cells are commonly used to isolate and propagate recombinant baculoviral stocks and to produce recombinant proteins. Gibco® Sf9 cells are adapted to serum-free suspension culture in Gibco® Sf-900™ II SFM, which saves significant time and expense associated with the adaptation of cultures

Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Cultures can be established between 5.0 x 10 4 and 1.0 x 10 5 viable cells/cm 2. Incubate cultures at 37°C The Sf9 cell line is a clonal isolate of IPLBSF21-AE (Sf21). The small, regular size makes them exceptional for the formation of monolayers and plaques. Sf21 cells are somewhat more disparate in size and form monolayers and plaques which are more irregular. Uses: Both cell lines are suitable for transfection, plaque purification, generating high-titer stocks, plaque formation, and expression.

Sf9 (Spodoptera frugiperda ovary) insect cells (Pharmingen, San Diego, CA) are grown in suspension in a shaking incubator (Innova 4000, New Brunswick Scientific, Edison, NJ) in IPL-41 medium (Gibco-Life Technologies, Rockville, MD) supplemented with 10% fetal bovine serum, 0.1% Pluronic F68 (Gibco-Life Technologies), gentamicin (50 μ g/ml) and Fungizone (50 μ g/ml) (Fungizone and gentamicin were from Gibco or the Tissue Culture Center, Washington University) Sf9 cells (Invitrogen) are maintained in Grace's medium supplemented with 10% fetal bovine serum (FBS) in spinner flasks (Bellco Biotechnology) at 27°. Cell densities are maintained between 0.5 and 3 × 106 cells/ml. Cell density doubles in approximately 24 h, and this growth rate should be monitored regularly The Sf9 cells are highly susceptible to baculovirus, which is widely used for expression of particular genes in the cultured insect cells. The expression of such genes lead to a robust production of proteins by Sf9 cells. In this protein expression process it is vital to know the concentration and viability of the Sf9 cells both for a healthy transfection as well as a robust protein production.

Cell Line Description Derived from pupal ovarian tissue of spodoptera frugiperda. The cells are highly susceptible to Baculovirus infection and are used in the production of protein products genetically manipulated into Baculovirus vector systems. Application Sf9 cell line has been used for Baculovirus viral studies Infecting the Sf9 cells with recombinant baculovirus resulted in a linear increase in volumetric productivity of beta-galactosidase up to 68-75 h of culture. Beyond this point almost no product was formed Sf9 cells are suspension cultures which are commonly used to isolate and propagate recombinant baculoviral stocks and to produce recombinant proteins. A key factor in the popularity of Sf9 and other insect cultures is the ability to produce large quantities of proteins that show post-translational modification typically exclusive to eukaryotes The Sf9 insect cell line is a clonal isolate derived from the parental Spodoptera frugiperda cell line IPLB-Sf-21-AE. Sf9 cells are adapted for suspension culture in ESF 921 or ESF AF and are available as a frozen vial or suspension culture.Sf9 cells are commonly used to produce recombinant baculoviral stocks and to produce recombinant proteins Viability of Sf9 cells after thawing can be low, i.e. 45% to 65% have been observed, regularly. However, the cells recover within 4 to 5 days to a confluence of 80 to 100%. Proliferating cultures: For transport, the cell culture flasks have been completely filled with culture medium to prevent loss of cells during transit

Of the cell lines available at Vigene, the Sf9 line allows the highest possible yields for AAV culture but is not suitable for adenovirus or lentivirus culture. Should I use my master cell bank or license one from Vigene Compared to Sf9 cells grown in yeastolate-containing media, ExpiSf9 cells grown in ExpiSf CD Medium achieved higher peak viable cell densities in standard shake flask cultures (>20 × 10 6 cells.

The following morphological changes are typical of monolayer Sf9 cells infected with recombinant AcNPV. 1. Early Phase:Infection begins with the adsorptive endocytosis of one or more competent virions by a cell in a high metabolic state (peak replication rate). The nucleocapsids pass through the cytoplasm to the nucleus Recently, Sf9 cells have also been used for research on apoptosis. Many substances, such as azadirachtin, abamectin, camptothecin, spinosad and ultraviolet, could induce apoptosis in Sf9 cells 6 - 9. Apoptosis is a normal physiological process for elimination of unwanted cells and works as a homeostatic mechanism in the development of multicellular organisms, and as the defense mechanism in. These cell lines include Sf9 and High Five , which are derived from the lepidopteran insects Spodoptera frugiperda (Sf) and Trichoplusia ni (Tn), respectively. Sf9 and High Five cells clearly have the machinery required for protein N-glycosylation, but cannot synthesize the same end products as mammalian cells (reviewed in refs

Formulation. Expression of genes in insect cells is more time-consuming than in bacteria. Therefore, one should be prepared for the case that one construct fails or does not yield enough protein. Similar to E. coli, the success rate is higher if you have several constructs to test rather than trying to optimize a single construct. Additionally, in case of Baculovirus constructs, protein yields can vary.

Sf9 cell line, derived from Spodoptera frugiperda, is used as a cell substrate for biological products and no viruses have been reported after extensive testing. We have used degenerate PCR assays and massively parallel sequencing (MPS) to identify a novel RNA virus belonging to the order Mononegavirales in Sf9 cells. Sequence analysis of the assembled virus genome showed the presence of five. Sf9 cell cycle dynamics were characterized by an initial G2/M arrest, which synchronized the cells and this feature was more pronounced for Hp than for Lp cells. CM addition decreased the initial arrest for Lp cultures, but did not affect Hp cells. Late in the culture, a final G2/M accumulation occurred. An octaploid population emerged during G2/M arrests.
