1 ethidium bromide (EB): We are more familiar. Strong mutagenic carcinogens, use disposable gloves must be worn, note that practices, it should not touch other items.
2. DEPC (DEPC): savory sweet smell, but the person does not blink! A powerful protein denaturant, and suspected carcinogen. Bottle when the bottle away from you, the internal pressure can lead to splashing. When you wear the appropriate gloves, wear overalls, and ventilated cupboard for the chemical.
3. PMSF (phenylmethylsulfonyl fluoride): a high-intensity toxic cholinesterase inhibitor. Its respiratory mucosa, eyes and skin have a very large destructive. May be due to inhalation, ingestion or skin absorption and deadly. Wear suitable gloves and safety glasses, and always used in the chemical ventilated cupboard. In case of contact, immediately flush with plenty of water glasses, or skin, the contaminated clothing discarded.
4 acetonitrile, volatile flammable, an irritant and chemical asphyxiant, fume hood, away from heat, fire.
5 actinomycin D, is a teratogen and carcinogen, fume hood.
6. Alpha-ibotenic toxic cyclic peptide, has strong toxicity, may be fatal.
7. N'N'-methylene-bis-acrylamide, toxic, affecting the central nervous system, do not inhale powder.
8 methanol, toxic, can cause blindness.
9 acid (concentrated): Because inhalation or skin absorption may be harmed, should wear gloves and goggles, the best in the chemical fume hood.
10 Ammonium persulfate: the mucous membranes and upper respiratory tract, eyes and skin and greater dangers, inhalation can be fatal. When wearing gloves, goggles. Always in a fume hood operation.
11 cesium chloride: may be due to inhalation, ingestion or skin absorption hazard to health. When wearing gloves and goggles.
12. DTT: a strong reducing agent, distributed odor. May be due to inhalation, ingestion or skin absorption hazard to health. When using solid or liquid when high concentrations of storage, wear gloves and goggles, in a fume hood operation.
13 Formaldehyde: highly toxic and volatile, but also a carcinogen, easily absorbed through the skin, eyes, mucous membranes and upper respiratory tract irritation and injury. As they avoid volatile aerosol. Wear gloves and goggles. Always in a fume hood operation. Keep away from heat, sparks and open flame.
14. Trizol: Irritating to eyes, skin corrosion. Once accidentally spilled a small drop in the face, immediately red, then, feel pain, we go a week later. If splashed, wash immediately with plenty of water.
Everyone in the laboratory, exposure to most chemicals are harmful, ultraviolet light, if the centrifuge is not good, then the noise pollution, VORTEX lead fingers need to shock, and so on, so everyone should pay attention to protect themselves, but not because of the easy way or the other reasons to relax the attention of security. The other is the attention to standards, engage in micro-organisms with particular attention, not to laboratory infection.
15 sodium azide, toxic, blocking the cytochrome electron transport system.
16 sodium fluoride, can be deadly toxic, fume hood.
17 radioactive material (isotope tag), to wear gloves, goggles, wear clothes, buy the best kit (if commercial).
18. Beta-mercaptoethanol, can be fatal, of respiratory, skin and eye damage.
19 methotrexate, carcinogenic and teratogenic.
20 formaldehyde, toxic, volatile, carcinogenic, irritating to eyes and respiratory tract injury, in a fume hood away from heat and fire.
21 bis-acrylamide, nerve agents, the cumulative effect.
22 Sodium dimethyl arsenic, carcinogenic, toxic.
23 streptomycin, carcinogenic, cause allergic reactions.
24 piperidine, toxic, affecting the eyes and respiratory tract, away from heat and fire.
25 putrescine, flammable, corrosive, away from heat and fire.
26 nickel sulfate, cancer, cause genetic damage.
27 hydrazine, toxic, explosive energy, heat and fire the yard.
