描述

The BACE1 protein is an important member of the aspartic protease family and is critical in Alzheimer's disease pathology.Alternative splicing generates multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to produce the mature protease.BACE1 Protein, Human (HEK293) is the recombinant human-derived BACE1 protein, expressed by HEK293 , with tag free.

研究背景

BACE1 是天冬氨酸蛋白酶肽酶 A1 家族的成员,在阿尔茨海默病病理学中发挥着关键作用。通过选择性剪接,该基因产生多种转录变体,其中至少一种编码前蛋白原,该前蛋白原经过蛋白水解加工产生成熟的蛋白酶。作为一种跨膜蛋白酶,BACE1 催化从淀粉样前体蛋白产生淀粉样β肽的初始步骤。β 淀粉样肽是阿尔茨海默病患者大脑中积累的β 淀粉样斑块的主要成分。BACE1 的表达很广泛,在多种组织中普遍存在,包括胰腺、大脑和 24 种其他组织,强调了其在不同生理环境中的重要性。

生物活性

Measured by its ability to cleave a fluorogenic peptide substrate, Mca-SEVNLDAEFRK(Dpn)RR-NH2. Read at excitation and emission wavelengths of 320 nm and 405 nm. The specific activity is 1.79 pmol/min/µg, as measured under the described conditions.

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)
× = ×
C1   V1   C2   V2

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
