Methotrexate disodium is an tetrahydrofolate dehydrogenase inhibitor

Oxyntomodulin (bovine, porcine) TFA is a 37-amino acid peptide hormone that functions as a glucagon-like peptide 1 (GLP-1) receptor agonist [1].

[D-Pro2] Spantide I TFA is an analog of Spantide I, serving as a selective antagonist of the NK1 receptor [1].

FITC-α-Bungarotoxin is the FITC-labeled form of α-Bungarotoxin, which acts as a competitive antagonist at nicotinic acetylcholine receptors (nAChRs) [1].

Biotin-α-Bungarotoxin is a biotinylated form of α-Bungarotoxin, which acts as a competitive antagonist at nicotinic acetylcholine receptors (nAChRs) [1].

Margatoxin TFA, an alpha-KTx scorpion toxin isolated from Centruroides margaritatus venom, is a 39-amino-acid peptide that serves as a high-affinity inhibitor of Kv1.3 (Kd = 11.7 pM). It also inhibits Kv1.2 (Kd = 6.4 pM) and Kv1.1 (Kd = 4.2 nM), making it a valuable tool for ion channel research [1] [2].

Biotin-β-Amyloid (1-42), human TFA, also known as Biotin-Amyloid β-Peptide (1-42) (human) TFA, is a biotin-labeled 42-amino acid peptide implicated in the pathogenesis of Alzheimer's disease.

AmmTX3 TFA, a peptide toxin derived from Androctonus mauretanicus scorpion venom, functions as a selective blocker of the K_v4 channel. It inhibits the A-type K^+ current with an inhibition constant (K_i) of 131 nM [1] [2].

ATX-II, an Na+ channel modulator toxin derived from the sea anemone (Anemonia sulcata), causes delayed inactivation of the Na+ channels and has been linked to pulmonary vein arrhythmogenesis and atrial fibrillation [1] [2]. It exhibits interaction with halothane, caffeine, and ryanodine.
