丙酮酸脱羧酶 (Pyruvate decaboxylase, PDC)又称α-羧化酶,是一种作用于α-酮酸是的羧化酶,丙酮酸脱羧酶 (PDC)、乙醇脱氢酶 (ADH)是乙醇发酵途径的关键酶,缺氧条件下二者均升高,PDC活性通常比ADH活性低,是乙醇合成的限速酶,无氧呼吸途径代谢产物的过程积累对细胞产生毒性,影响线粒体结构和三羧酸循环的相关酶活性。
丙酮酸脱羧酶 (PDC)提取试剂主要用于裂解植物组织,提取样品中的丙酮酸脱羧酶。该试剂仅用于科研领域,不适用于临床诊断或其他用途。

自备材料:
1、蒸馏水
2、离心管或试管、匀浆器或研钵、低温离心机
操作步骤 (仅供参考):
1、取植物组织清洗干净,切碎。
2、配制丙酮酸脱羧酶提取工作液:取出丙酮酸脱羧酶提取试剂和PMSF,恢复至室温,按丙酮酸脱羧酶提取试剂: PMSF=499: 1的比例混合,混匀,即配即用,不易久置,否则蛋白酶抑制剂PMSF的效率会有所下降。
3、按植物组织: 丙酮酸脱羧酶提取工作液=1 g: 4 ml的比例,加入预冷的丙酮酸脱羧酶提取工作液,冰浴情况下充分匀浆或研磨。
4、12000 g,4 ℃离心20 min,留取上清液即为丙酮酸脱羧酶粗提液,4 ℃保存,用于丙酮酸脱羧酶的检测或其他用途。
计算:
样品粗酶液获得率 (ml/g)=上清液体积 (ml)/样品质量 (g)×100%
注意事项:
1、实验材料应尽量新鲜,如取材后不立即使用,应存于-20~-80 ℃。
2、待测样品中不能含有磷酸酶抑制剂,同时需避免反复冻融。
3、所测样本的值高于标准曲线的上限,应用丙酮酸脱羧酶提取工作液稀释样品后重新测定。
4、试剂开封后请尽快使用,以防影响后续实验效果。
5、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Pyruvate decarboxylase (PDC), also known as α‑carboxylase, is a carboxylase acting on α‑keto acids. Pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH) are key enzymes in the ethanol fermentation pathway. Both are up‑regulated under hypoxic conditions. PDC activity is generally lower than ADH activity, making it the rate‑limiting enzyme for ethanol synthesis. The accumulation of metabolites from the anaerobic respiration pathway is toxic to cells, affecting mitochondrial structure and the activities of enzymes involved in the tricarboxylic acid cycle.
Pyruvate Decarboxylase (PDC) Extraction Reagent is mainly used for lysing plant tissues and extracting pyruvate decarboxylase from samples.This reagent is for research use only and is not suitable for clinical diagnosis or other applications.

Materials Provided by User
1. Distilled water
2. Centrifuge tubes or test tubes, homogenizer or mortar, refrigerated centrifuge
Protocol (For Reference Only)
1. Collect plant tissue, clean thoroughly, and mince.
2. Prepare working solution of Pyruvate Decarboxylase Extraction Reagent:
Take Pyruvate Decarboxylase Extraction Reagent and PMSF to room temperature. Mix at a ratio of Pyruvate Decarboxylase Extraction Reagent: PMSF=499: 1. Use immediately after preparation; prolonged storage reduces the inhibitory efficiency of PMSF.
3. Mix minced plant tissue with pre‑cooled working solution at a ratio of plant tissue: working solution=1 g: 4 mL. Homogenize or grind thoroughly in an ice bath.
4. Centrifuge at 12000 × g, 4 °C for 20 min. The supernatant is the crude pyruvate decarboxylase extract. Store at 4 °C for PDC detection or other analyses.
Calculation
Crude Enzyme Extract Yield (mL/g)=Supernatant Volume (mL)/Sample Weight (g) × 100%
Precautions
1. Use fresh experimental materials whenever possible. If not used immediately, store at −20 to −80 °C.
2. Test samples must not contain phosphatase inhibitors; avoid repeated freeze‑thaw cycles.
3. If sample readings exceed the upper limit of the standard curve, dilute the sample with PDC extraction working solution and re‑assay.
4. Use the reagent promptly after opening to avoid compromising experimental performance.
5. For your safety and health, wear a lab coat and disposable gloves during operation.
