Outline the major steps for how TLR 4 might activate SAPK pathway. Outline the steps necessary for preparing a cell lysate The instructions in a protocol indicate that a 1/10,000 dilution of a stock solution is to be made in water. This means 1 part of stock solution and 9,999 parts of water. If you equate 1 part as 1 ml, this would mean that we would end up with 10,000 ml (= 10 liters) of the diluted solution which...
