SDS is a solid, so a 10% solution will be 10% weight of SDS in water, 10g per 100ml

The weights and volumes aren't critical.

Are you a student or working in a lab?

What background do you have?

Put it in the freezer.

One other reason, not talked about so far, is that childhood vaccination, ( of girls ) against measles means as women, they are immune to measles during pregnancy. Measles during pregnancy gives a very high risk of brain damage to the unborn child. I have heard that in the UK, the cost of the vaccine for the whole country is less than the cost of looking after a brain damaged child for its whole life.

If you want to get the gold out, simply add more water to dilute the binder, the gold will then fall the bottom of the container and you can simply pour off the water.

BTW there isn't a lot of gold in the paint. It is VERY thin foil, hence it is easily suspended in the paint. I'm afraid you aren't going to get rich.

I hope that you and your mom know that aqua regia isn't trivial stuff to play around with. Are you really 11?

Do you REALLY need to sequence this protein or just get an N-terminal sequence done - very different proposition?

An N-term sequence will give you enough info to get a DNA primer done and to search the databases. It is far easier and faster to sequence DNA than protein. Don't forget that to do a full protein sequence you will need a large amount of material.
