Common Cell Culture Problems: Poor Attachment of Adherent Cells -- Healthy and appropriately nourished cells re-engineer and optimize their attachment matrices. Cells that are cultured under suboptimal growth conditions attach poorly. When the culture surface provided is appropriate, the most common cause of failure of cells to attach to a substrate is environmental stress placed on the cells

Ammonium Sulfate | Aluminum Sulfate | Aluminum …
Ammonium sulfate is potentially dangerous to both people and the environment, so it requires care in its use. It can cause severe irritation and inflammation of the respiratory tract if inhaled. Eating or drinking ammonium sulfate will cause irritation in the gastrointestinal tract like nausea, vomiting, and diarrhea, although it isn’t toxic unless consumed in large quantities.
Strong Electrolytes and Weak Electrolytes Chemistry Tutorial
Sodium hydroxide is a strong electrolyte because it it is the hydroxide of a Group 1 metal. Is your answer plausible? Sodium hydroxide, NaOH (s), is used in drain cleaners. It is an ionic solid made up of sodium ions, Na +, and hydroxide ions, OH-. When added
Construction Dust Zinc can be installed adjacent to limestone. Limestone buildings in Paris have had numerous zinc protective flashings between floors for decades. The run off from limestone onto zinc material is acceptable. However, limestone dust and gypsum dust generated during cutting operations can react with zinc in the presence of water and form a superficial layer of white rust.
