Lambda (written λ, in lowercase) is a non-SI unit of volume equal to 10 −9 m 3, 1 cubic millimetre (mm 3) or 1 microlitre (μL). Introduced by the BIPM in 1880, [ 1 ] the lambda has been used in chemistry [ 2 ] and in law for measuring volume, but its use is not recommended.
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these.
The SI unit of molar absorption coefficient is the square metre per mole (m 2 /mol), but in practice, quantities are usually expressed in terms of M −1 ⋅cm −1 or L⋅mol −1 ⋅cm −1 (the latter two units are both equal to 0.1 m 2 /mol). In older literature, the cm 2 /mol is sometimes used; 1 M −1 ⋅cm −1 equals 1000 cm 2 /mol.
The variable (V) domain of light chains has a high degree of structural diversity, particularly the antigen-binding region. In addition, the first 23 amino acids of the 1st variable domain framework region have a number of variations known as subgroups. Four kappa (Vκ1–Vκ4) and six lambda subgroups (Vλ1–Vλ6) can be identified. [1]
The approximate length of a light chain protein is from 211 to 217 amino acids. [3] The constant region determines what class (kappa or lambda) the light chain is. [ 8 ] The lambda class has 4 subtypes ( λ {\displaystyle \lambda } 1 , λ {\displaystyle \lambda } 2 , λ {\displaystyle \lambda } 3 , and λ {\displaystyle \lambda } 7 ).
The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. [1] Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused ...
C 0 is the electrolyte concentration in molar units (M or mol/L). Alternatively, κ − 1 = 1 8 π λ B N A × 10 − 24 I {\displaystyle \kappa ^{-1}={\frac {1}{\sqrt {8\pi \lambda _{\text{B}}N_{\text{A}}\times 10^{-24}I}}}} where λ B {\displaystyle \lambda _{\text{B}}} is the Bjerrum length of the medium in nm, and the factor 10 − 24 ...
When a 1-to-1 (one mole of reactant gives one mole of product) chemical reaction (including equilibria) involves a pair of substances with an isosbestic point, the absorbance of the reaction mixture at this wavelength remains invariant, regardless of the extent of reaction (or the position of the chemical equilibrium).
