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.
Authors:Endo T; Ohta K; Haraguchi K; Onaya T;
Journal:J Biol Chem
PubMed ID:7738021
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
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
Structural basis of G protein specificity of human endothelin receptors. A study with endothelinA/B chimeras.
'The endothelin (ET) family of peptides acts via two subtypes of guanine nucleotide-binding regulatory protein (G protein)-coupled receptors termed ETA and ETB. ET-1 stimulated cAMP formation in Chinese hamster ovary (CHO) cells stably expressing human wild-type ETA (CHO/hETA cells) while it inhibited cAMP formation in CHO cells expressing human wild-type ...

A region of human CD14 required for lipopolysaccharide binding.
Authors: Viriyakosol S; Kirkland T N;
Journal:J Biol Chem
PubMed ID:7529231
'CD14, a glycosylphosphatidylinositol-anchored protein on the surface of monocytes, macrophages, and polymorphonuclear leukocytes, is a receptor for lipopolysaccharide (LPS). CD14 binding of LPS is enhanced by serum proteins, especially lipopolysaccharide binding protein. The serum-dependent binding of LPS to CD14 stimulates macrophages to make cytokines, which can cause septic shock in ... More
Mechanisms of desensitization and resensitization of proteinase-activated receptor-2.
Authors: Böhm S K; Khitin L M; Grady E F; Aponte G; Payan D G; Bunnett N W;
Journal:J Biol Chem
PubMed ID:8703006
'Proteinase-activated receptor-2 (PAR-2) is a G-protein-coupled receptor that is expressed by intestinal epithelial cells, which are episodically exposed to pancreatic trypsin in the intestinal lumen. Trypsin cleaves PAR-2 to expose a tethered ligand, which irreversibly activates the receptor. Thus, PAR-2 may desensitize and resensitize by novel mechanisms. We examined these ... More
