Which of your antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for stable selection in mammalian cells?
All of our antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for making multiple stable cell lines. However, kill curves will need to be performed for each combination of antibiotics since sensitivity to a given antibiotic tends to increase when combined with other antibiotics.
Can Neomycin be used in mammalian selection? Can Neomycin be used instead of Kanamycin in bacterial selection?
No, Neomycin is toxic to mammalian cells. It also causes irreversible damage to kidneys and other organs. Geneticin (aka G418 Sulfate) is a less toxic and very effective alternative for selection in mammalian cells. Neomycin can be used in bacterial selection, but Kanamycin is the preferred drug to use because of Neomycin's toxicity.
Cloning and functional expression of a thyrotropin receptor cDNA from rat fat cells.

Thyrotropin receptor (TSH-R) has been thought to be thyroid-specific, but, by Northern blot analysis, we found that rat adipose tissue expressed TSH-R mRNAs in amounts approaching those in the thyroid. To investigate the function of TSH-R from adipose tissue, we screened a rat fat cell lambda gt11 cDNA library for ... More
The large size (six membrane-spanning repeats in each of four domains) and asymmetric architecture of the voltage-dependent Na+ channel has hindered determination of its structure. With the goal of determining the minimum structure of the Na+ channel permeation pathway, we created two stable cell lines expressing the voltage-dependent rat skeletal ... More
Synaptotagmin V is targeted to dense-core vesicles that undergo calcium-dependent exocytosis in PC12 cells.
'Synaptotagmins (Syts) III, V, VI, and X are classified as a subclass of Syt, based on their sequence similarities and biochemical properties (Ibata, K., Fukuda, M., and Mikoshiba, K. (1998) J. Biol. Chem. 273, 12267-12273; Fukuda, M., Kanno, E., and Mikoshiba, K. (1999) J. Biol. Chem. 274, 31421-31427). Although they ... More
Src-dependent phosphorylation of the epidermal growth factor receptor on tyrosine 845 is required for zinc-induced Ras activation.

'Previous studies have shown that exposure of cells to Zn2+ ions induces Ras and MAPK activation through the EGF receptor (EGFR). To further determine the role of EGFR in Zn2+-induced signaling, mouse B82L fibroblasts expressing no detectable EGFR protein (B82L-par), wild type EGFR (B82L-wt), kinase-deficient EGFR (B82L-K721M), or COOH-truncated EGFR ...

Residues throughout the cytoplasmic domain affect the internalization efficiency of P-selectin.

Journal:J Biol Chem
PubMed ID:7592923
'The cytoplasmic domains of many membrane proteins have short sequences, usually including a tyrosine or a di-leucine, that function as sorting signals. P-selectin is an adhesion receptor for leukocytes that is expressed on activated platelets and endothelial cells. Its 35-residue cytoplasmic domain contains signals for sorting into regulated secretory granules, ... More
