Concentration is in mg/ml, %, or molarity depending on which type coefficient is used. To construct a Hb-based nanoplatform for tumor-targeted oxygen delivery, human serum albumin (HSA), the most abundant plasma protein showing complete biocompatibility, non-toxicity and low immunogenicity, as well as in vivo stability and stimuli-responsive properties, was chosen as a building block for fabricating a protein-based hybrid. Now, let's take this one step at a time. 87 Ci/L) for Concentration on the date of use. Home Contact About Order News Terms. 15 torr, what is the molar mass (g/mol) of the protein? ok so I converted 1. The Selleck molarity calculator is based on the following equation:. The molar ratio of protein 1 to protein 2 was obtained by dividing the molar portion of protein 1 with the The nominal molar ratios (the known molar ratios of the molar portion of protein 2. Protein molecular weight [kDa]:. What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197. The “molar absorption coefficient (ϵ molar)” refers to the absorbance of light per unit path length and per unit of concentration expressed in “moles per liter.
