Esta solución contiene 10.000 unidades/ml de penicilina y 10.000 µg/ml de estreptomicina. Los antibióticos penicilina y estreptomicina se usan para impedir la contaminación bacteriana de los cultivos celulares debido a su eficaz acción combinada contra bacterias grampositivas y gramnegativas. La penicilina se purificó en un principio a partir de los hongos Penicillium y actúa mediante una interferencia directa con el volumen de la pared celular bacteriana, e indirecta mediante la activación de la liberación de enzimas que alteran aún más la pared celular. La estreptomicina fue originalmente purificada a partir de Streptomyces griseus. Actúa mediante la creación de una unión a la subunidad 30S del ribosoma bacteriano, lo que inhibe la síntesis de proteínas y la muerte de las bacterias susceptibles.

Yes, this is normal and will not affect the potency or application of the product. This solution is typically colorless. However, it can have a pink to yellow color tint. The coloring is a carry-over from the manufacturing process of Streptomycin - the genus that Steptomycin is isolated from (Actinomycetes Streptomyces griseus) is responsible for a wide variety of pigments.

When an irreplaceable culture becomes contaminated, researchers may attempt to eliminate or control the contamination.

1. Determine if the contamination is bacteria, fungus, mycoplasma, or yeast. Read more here to view characteristics of each contaminant.
2. Isolate the contaminated culture from other cell lines.
3. Clean incubators and laminar flow hoods with a laboratory disinfectant, and check HEPA filters.
4. Antibiotics and antimycotics at high concentrations can be toxic to some cell lines. Therefore, perform a dose-response test to determine the level at which an antibiotic or antimycotic becomes toxic. This is particularly important when using an antimycotic such as Gibco Fungizone reagent or an antibiotic such as tylosin.

The following is a suggested procedure for determining toxicity levels and decontaminating cultures:

1. Dissociate, count, and dilute the cells in antibiotic-free media. Dilute the cells to the concentration used for regular cell passage.
2. Dispense the cell suspension into a multiwell culture plate or several small flasks. Add the antibiotic of choice to each well in a range of concentrations. For example, we suggest the following concentrations for Gibco Fungizone reagent: 0.25, 0.50, 1.0, 2.0, 4.0, and 8.0 µg/mL.
3. Observe the cells daily for signs of toxicity such as sloughing, appearance of vacuoles, decrease in confluency, and rounding.
4. When the toxic antibiotic level has been determined, culture the cells for two to three passages using the antibiotic at a concentration one- to two-fold lower than the toxic concentration.
5. Culture the cells for one passage in antibiotic-free media.
6. Repeat step 4.
7. Culture the cells in antibiotic-free medium for four to six passages to determine if the contamination has been eliminated.

Abstract
Identification of a novel redox-sensitive gene, Id3, which mediates angiotensin II-induced cell growth.
Authors:Mueller Cornelius; Baudler Stephanie; Welzel Hilke; Böhm Michael; Nickenig Georg;
Journal:Circulation
PubMed ID:12021231
BACKGROUND: Reactive oxygen species, such as superoxide (O(2)(-)), are involved in the abnormal growth of various cell types. Angiotensin II (Ang II) is one of the most potent inducers of oxidative stress in the vasculature. The molecular events involved in Ang II-induced proliferation of vascular smooth muscle cells (VSMCs) are ... More

'Bruton''s tyrosine kinase (Btk), a member of the Tec family of protein-tyrosine kinases, has been shown to be crucial for B cell development, differentiation, and signaling. Mutations in the Btk gene lead to X-linked agammaglobulinemia in humans and X-linked immunodeficiency in mice. Using a co-transfection approach, we present evidence here ... More

'The Salmonella outer membrane protein Rck mediates a Zipper entry mechanism controlled by tyrosine phosphorylation and class I phosphatidylinositol 3-kinase (PI 3-kinase). However, the underlying mechanism leading to this signaling cascade remains unclear.

'Developmental decisions that control cell fate are commonly regulated by the Notch signaling pathway. Activation of transmembrane Notch receptors results in proteolytic liberation of the intracellular domain of Notch, which translocates into the nucleus, binds a repressor (C promoter binding factor 1/RBP-Jkappa, Su(H), and Lag-1 (CSL)), and induces target genes. ... More

'Endotoxin (lipopolysaccharide, LPS) is a component of the outer membrane of Gram-negative bacteria and promotes the activation of macrophages and microglia. Although these cells are highly LPS-responsive, they serve unique tissue-specific functions and exhibit different LPS sensitivities. Accordingly, it was of interest to evaluate whether these biological differences reside in ... More
