bapta-am

BAPTA-AM 是一种钙离子螯合剂，具有细胞渗透性和选择性，可以阻断 hERG、hKv1.3 和 hKv1.5 通道 (IC50=1.3 1.45 1.23 μM)。BAPTA-AM对 Ca2+的亲和力是 Mg2+的 105 倍，可以用于钙在细胞信号传导中的作用。

BAPTA, tetrapotassium salt is a Ca2+ chelator.

Calcium Green BAPTA-2 AM serves as a fluorescent indicator for calcium ions.

FG 488 BAPTA-2 AM, a calcium-specific reporter dye, is utilized for detecting calcium concentration.

5-Nitro BAPTA, a calcium chelator, combined with 2-Me-substituted TM (as a fluorescent moiety), forms a red fluorescent probe (CaTM-2 AM) for imaging cytoplasmic Ca 2+ in cultured living cells. It serves as a building block for synthesizing Ca 2+ specific chelators, Ca 2+ buffers, and fluorescent Ca 2+ indicators [1] [2].

5-Nitro BAPTA tetramethyl ester是一种钙螯合剂，用于双光子探针合成，实现细胞内钙离子实时成像，可检测肝组织内100-300 μm深度的钙波，持续1100-4000 s，并可与2-Me取代TM荧光化合物结合，制成红色荧光探针。

Oregon-BAPTA Green 1AM（Oregon Green 488 BAPTA 1AM）是一种荧光Ca2+指示剂，由绿色荧光探针OG 488和可透过细胞膜的Ca2+螯合剂BAPTA AM组成。
