描述

SLC21A3 is a Na(+)-independent transporter that greatly facilitates cellular uptake of a variety of organic anions, including bile salts necessary for intestinal absorption. SLC21A3 is responsible for transporting substances such as DHEAS, estrone 3-sulfate, and atROL in human retinal pigment epithelial cells to maintain the integrity of the visual cycle. SLC21A3 Protein, Human (Sf9, His, MBP, FLAG) is the recombinant human-derived SLC21A3 protein, expressed by Sf9 insect cells , with N-MBP, C-Flag, N-8*His labeled tag. The total length of SLC21A3 Protein, Human (Sf9, His, MBP, FLAG) is 669 a.a., .

研究背景

SLC21A3 是一种不依赖 Na(+) 的转运蛋白,可促进细胞在质膜上摄取多种有机阴离子,包括未结合和结合的胆汁盐,例如胆酸盐、脱氧胆酸盐、牛磺胆酸盐和甘胆酸盐。该转运蛋白对于肠道吸收胆汁酸至关重要,负责吸收 3-硫酸脱氢表雄酮 (DHEAS)、3-硫酸雌酮、17β-雌二醇 17-O-(β-D-葡萄糖醛酸)和全反式-视黄醇(atROL)穿过人类视网膜色素上皮,对于维持视觉周期完整性和视力至关重要。此外,SLC21A3 介导临床使用的药物、甲状腺激素(T3 和 T4)、前列腺素 E2 和神经肽(如物质 P/TAC1 和血管活性肠肽/VIP)的转运。它涉及有机阴离子和信号介质的血脑和脑脊液屏障转运、神经细胞对激素的摄取,并可能有助于调节睾丸中有机化合物穿过血睾屏障的转运。此外,SLC21A3 表现出 pH 敏感的底物特异性,碳酸氢根/HCO3(-) 可能作为有机阴离子交换中的抗衡阴离子,表明其在酸性微环境中的底物运输中发挥作用。该蛋白还可能在化疗药物(例如甲氨蝶呤和紫杉醇)的血浆和组织分布中发挥作用。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
