D-Cysteic acid

D-Cysteic acid is a competitive inhibitor of the aspartate:alanine antiporter (AspT) from Tetragenococcus halophilus. For L-aspartate self-exchange, D-Cysteic acid has a K_i of 0.14 mM and an IC₅₀ of 0.19 mM; for L-alanine self-exchange, it has a K_i of 5.0 mM and an IC₅₀ of 9.0 mM. D-Cysteic acid occupies a distinct substrate-binding site within the substrate transport pathway of AspT, preventing the binding of natural substrates to the transporter. D-Cysteic acid can be used in studies related to substrate recognition and transport mechanisms of transporters.

製品説明

体外実験

D-cysteic acid competitively inhibits L-aspartate and L-alanine self-exchange via reconstituted Tetragenococcus halophilus AspT, with greater potency against L-aspartate self-exchange (K_i = 0.14 mM; IC₅₀ = 0.19 mM) than L-alanine self-exchange (K_i = 5.0 mM; IC₅₀=9.0 mM)^[1].
D-Cysteic acid is formed via oxidation of L-cysteine with performic acid at 50°C for 15 min^[2].

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
