Abstract

Several caged calciums have been synthesized since 1986, and three are commercially available: DM-nitrophen, NP-EGTA, and nitr-5. Each of these caged compounds has uniquely useful properties, making the choice of which cage to use dependent on the specific experiment (i.e., the cell type and divalent cation requirements of the experiments within purview). Significantly, methods have been developed for all three cages that permit their quantitative use inside many cell types, including those with some of the most demanding of requirements for experiments with caged calcium, namely, in relating presynaptic [Ca] to post-synaptic function.19,72 The success of such experiments using DM-nitrophen and NP-EGTA suggests that caged calcium is now a mature tool for cellular physiology and neurobiology.

      Among the most successful applications of a commercially available caged compound is the photorelease of calcium ions from DMNP-EDTA (1-(2-nitro-4,5-dimethoxyphenyl)-N,N,N′,N′-tetrakis[(oxycarbonyl)methyl]-1,2-ethanediamine, DM-nitrophen) (Kaplan and Ellis-Davies, 1988). DMNP-EDTA-Ca has been used extensively in neurobiology, e.g., for the detailed investigation of synapse functionality (Ellis-Davies, 2003). Its success can be traced to the fact that it combines several features desirable for using caged compounds in biological environments, which include (i) no (or low) toxicity, (ii) stability in aqueous solutions, (iii) low premature release of the effector, biocompatible release wavelengths (λ > 300 nm), (iv) large extinction coefficients and high quantum yields, and (v) quantitative release of the effector molecule.

      Citation Excerpt :

      Of the most commonly used and commercially available caged-Ca2+ compounds DMn seems to be the best choice to release caged-Ca2+ when rapid and large increases in [Ca2+] are desired. First of all, DMn has the highest affinity for Ca2+ (Kd = 5 nM, the next best, NP-EGTA, has a Kd of 80 nM), and its PPs have the lowest affinity for Ca2+ after photolysis [60,61]. Consequently, about 95–99% of DMn is occupied with Ca2+ while the [Ca2+]rest is at 0.1–1 μM, and most of the bound Ca2+ will be released from the PPs.
