If I mix clindamycin HCL in DMSO liquid, how long is it good for?

DMSO is a stabilizing agent, thus I would expect it would be good for many weeks, if not months- The more important concern would be temperature.  Keep it at around freezing, and it'll stay for a good long time.

liquids develop bacteria so a year is considered the safe limit.\nWith dry pills and powders that were stored out of sunlight, they are safe and effective for 10 years or more!

neosporin works great, but it tastes nasty...  just put it on when you go to bed

i take avonex. out of refrigeration for 24 hours? it is totally useless and a waste of $500.00.  avonex is supposed to be refrigerated and only out of the fridge long enough to warm to body temp for injection. the longest mine has ever been out of refrigeration was 4 hours when our power went out, but i had it in a cooler on ice.\nafter 12 hours of no refrigeration, again, it is useless and a waste of $500.00 for 1 shot. but, there are 2 kinds of avonex, i use the prefilled syringe. there is also the kind that has to be mixed. i assume that you are talking about the prefilled syringe.

You should let it set in a jug for at least 24 hours before using so that chemicals in it can evaporate.

It depends on what method of chlorine disinfection you use. Disinfecting not only depends on the initial reations, but the byproducts created. Those initial reactants are highly reactive, therefore they are very effective disinfectants, but don't last long in the water to supply to keep disinfecting. The byproducts created last longer, but aren't as effective. Disinfection depends on two things: concentration and exposure time.\n\nIf using chlorine bleach, 10 drops will be needed per liter at 1%-3% concentration. 2 drops per liter at 4%-6% concentration. And 1 drop per liter at 7%-10% concentration. The treated water should be mixed thoroughly and allowed to stand, preferably covered, for 30 minutes. The water should have a slight chlorine odor; if not, repeat the dosage and allow the water to stand for an additional 15 minutes. If the treated water has too strong a chlorine taste, it can be made more pleasing by allowing the water to stand exposed to the air for a few hours or by pouring it from one clean container to another several times.\n\nGranular calcium hypochlorite. To disinfect water, add the chlorine solution in the ratio of one part of chlorine solution to each 100 parts of water to be treated. This is roughly equal to adding 1 pint (480 mL) of stock chlorine to each 50 liters of water to be disinfected. To remove any objectionable chlorine odor, aerate the water as described above.

If you add DCl or DNO3 to D2O, you will get D3O+.\nD3O will not be stable and very hard to make.

Lincomycin hydrochloride is mainly used for fighting respiratory tract and soft tissue infections. \n\nthere's another type:  It is indicated for the infections due to Staphylococcus,Streptococcus Pneumococcus and anaerobes. It may cause enteritis of pseudo-menbrane after prolonged administration. Patients with hepatic insufficiency should use prudently. \n\nLidocaine hydrochloride is used as a pain reliever. Lidocaine (lignocaine) belongs to a group of medicines known as local anaesthetics. Lidocaine acts to block temporarily the pathway of pain impulses along nerve fibres. This relieves or prevents pain in the area where it has been injected. This preparation is injected to provide local anaesthesia for minor procedures, such as dental surgery. \n\n\nyou can check out these websites. it's good. good luck!

I did a bit of research on the net to see what I could find out.\n\nI focused on the sites that were not trying to sell the product so nothing to gain by any information provided.\n\nHere are a couple sites that I found:\n\n(1) http://www.pdrhealth.com/drug_info/nmdrugprofiles/herbaldrugs/101270.shtml\n\n(2) http://au.health.yahoo.com/041101/25/1umx.html?r=967507925\n\n\n\nIt seems it is not recommended to use in this day and age and if used should be done under medical supervision only. \n\nIt has been noted that overdose reaction in sheep is “spasms, paralysis, and death through asphyxiation” (1)\n“Possible side effects include headache, weakness, jitteriness, yellow-green saliva.”(2)\n\n\nIt is contraindicated for pregnant and lactating women and for children and infants (2)\n\n\nI  scanned through a number of  other sites but unable to find anything specific to men or to any specific affect adverse or other wise specifically to men.

Yes. If its after a year, then I would throw it out.  Usually there is an expiration date somewhere on the bottle. But it doesn't work if it is old.  Hope this helps!

Which method of deaeration are you using?  It makes a big difference.  Definitely less than 0.1 mg/L.

most expired meds just lose their potency.  a few weeks to a couple of months past the expiration date and they will still be ok.  anything over 6 months should be tossed out.  make sure to remove your label first so someone can't find your personal info if they decide to rummage through your trash

order from Invitrogen or some biotech company for a bottle of DMEM...thats what most labs do nowdays.\n\nWhen preparing a DMEM for mammalian cells, you should have Foetal Calf Serum or Bovine serum and some antibiotics (e.g penicillin/streptomycin/glutamine) depending on ur cell type.

There is NO way for anyone to answer that without knowing the relative concentrations of active ingredients in both the pills and the liquid.  There are too many different sizes of pills and strengths of liquids to make anything resembling an accurate guess.
