Recipes for stock solutions and general use buffers
people.virginia.eduRecipes for stock solutions and general use buffers How to determine volumes to use to obtain a certain concentration: • C 1V 1 = C 2V 2 where C = concentration and V = volume • Make sure to match units! • Example: You have a stock solution at 100 mg/mL. You want 75 mL at 150 µg/mL.
Protocols and tips in protein purification
www.sheffield.ac.ukPreparation and use of stock solutions It is very convenient to have stock solutions of the main salts and buffers used during purification. Correctly and carefully prepared stock solutions can noticeably improve accuracy and reproducibility of the purification procedures. Stock solution preparation sequence

iti.stanford.eduSoluble in aqueous buffers, or add directly to extraction media. Alternatively, prepare 7x stock solutions in 1.5 ml water or 100 mM phosphate buffer, pH 7.0. Stock solution is stable for 1-2 weeks at 2-8°C or at least 12 weeks at -15 to -25°C. Can be used in thiol-contain-ing solutions at room temperature. Soluble in aqueous buffers, or add
EdU (5-ethynyl-2’-deoxyuridine)
tools.thermofisher.comPreparing Stock Solution EdU is readily soluble in DMSO, alcohol, water, or aqueous buffers. For use with in vitro applications, prepare 10 mM EdU stock solution in DMSO or aqueous buffer. Store 10 mM EdU stock solution at ≤–20˚C for one year. EdU has a characteristic 288 nm absorption peak which can be used to accurately quantitate

www.ccri.eduBuffers: Solutions which undergo only a small change in pH when small quantities of acid or base are added to them are called buffers. For example, human blood is a complex buffered mixture with a normal pH range of 7.35-7.45. Three different buffer systems keep blood pH from varying more than ± 0.1 unit.

depts.washington.eduCAUTION: DO NOT add bleach or acidic solutions directly to the sample-preparation waste. The sample-preparation waste contains guanidine hydrochloride from Buffers AL and AW1, which can form highly reactive compounds when combined with bleach. If liquid containing these buffers is spilt, clean with suitable laboratory detergent and water.

Filter the sample through a 0.22 µm or a 0.45 µm filter and/or centrifuge it immediately before applying it to the column.
PROTEINS (LOWRY) PROTOCOL 1. INTRODUCTION
web.itu.edu.trAlso at the protocol given by Gerhardt et al. (1994), the concentration of the stock standard solution is given as 500 mg/L, instead of 100 mg/L. Though since we’re preparing the stock solution fresh every time, I think we can continue to prepare a stock solution of 100 mg/L, if we continue to use the above range for the standard curve.
