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
The connecting segment between both epidermal growth factor-like domains in blood coagulation factor IX contributes to stimulation by factor VIIIa and its isolated A2 domain.

PubMed ID:11925427
The light chain of activated factor IX comprises multiple interactions between both epidermal growth factor-like domains that contribute to enzymatic activity and binding of factor IXa to its cofactor factor VIIIa. To investigate the association between factor IXa-specific properties and surface-exposed structure elements, chimeras were constructed in which the interconnection ... More
DBC2, a candidate for a tumor suppressor gene involved in breast cancer.

PubMed ID:12370419
A previously uncharacterized gene, DBC2 (deleted in breast cancer), was cloned from a homozygously deleted region at human chromosome 8p21. DBC2 contains a highly conserved RAS domain and two putative protein interacting domains. Our analyses indicate that DBC2 is the best candidate tumor suppressor gene from this region. It lies ...

Role of tyrosine kinase Jak2 in prolactin-induced differentiation and growth of mammary epithelial cells.
Authors:Xie Jianwu; LeBaron Matthew J; Nevalainen Marja T; Rui Hallgeir;
Journal:J Biol Chem
PubMed ID:11821424
Genetic studies in mice have established a critical role for prolactin receptors and transcription factor Stat5 in mammary gland differentiation. However, the enzymatic coupling between prolactin receptors and Stat5 in this process has not been established. In addition to Jak2, several other tyrosine kinases reportedly also are associated with prolactin ... More
A functional role for the B56 alpha-subunit of protein phosphatase 2A in ceramide-mediated regulation of Bcl2 phosphorylation status and function.
Authors: Ruvolo Peter P; Clark Warren; Mumby Marc; Gao Fengqin; May W Stratford;
Journal:J Biol Chem
PubMed ID:11929874
'Recently it has been shown that the potent apoptotic agent ceramide activates a mitochondrial protein phosphatase 2A (PP2A) and promotes dephosphorylation of the anti-apoptotic molecule Bcl2 (Ruvolo, P. P., Deng, X., Ito, T., Carr, B. K., and May, W. S. (1999) J. Biol. Chem. 274, 20296-20300). In cells expressing Bcl2, ... More
