您说:
LDH5和LDHA是同一个蛋白吗,如果我要买纯化蛋白做体外酶活实验,步骤参考这个Biochemical Assays. LDHA Biochemical Assay. Briefly, 3 μL of
human lactate dehydrogenase 5 (no. A38558H, Meridian Life Science,
Inc., Memphis, TN) in LDH assay buffer (200 mM Tris HCl, pH 7.4,
100 μM EDTA, and 0.01% Tween-20) was added to a black solid
bottom 1536-well assay plate (Greiner Bio-One) using a BioRAPTR
FRD dispenser (Beckman Coulter, Brea, CA). A 1536-well pintool
dispenser outfitted with 20 nL pins (Wako Automation, San Diego,
CA) was used to transfer 23 nL of DMSO-solubilized compound
(both library and vehicle controls) to each 1536-well assay plate.
Following compound transfer, 1 μL of substrate solution containing
NADH and sodium pyruvate (Sigma-Aldrich, St. Louis, MO) in LDH
assay buffer was dispensed via BioRAPTR FRD to initiate the reaction.
Final concentrations in the 4 μL reaction volume were 2 nM LDHA
enzyme, 0.06 mM NADH, and 0.2 mM sodium pyruvate. Following a
5 min incubation period at room temperature, 1 μL of detection
reagent (C. kluyveri diaphorase (Sigma-Aldrich) and resazurin sodium
salt (Sigma-Aldrich) in LDH assay buffer) was added to a total volume
of 5 μL. Final concentrations of detection reagents were 0.133 mg/mL
diaphorase and 37 μM resazurin. Plates were immediately transferred
to a ViewLux microplate imager (PerkinElmer, Waltham, MA), and
any resulting resorufin fluorescence was measured (ex 540 nm, em 590
nm) at 0 and 20 min. Fluorescence was normalized using enzyme-free
and DMSO-treated control wells on each plate.
LDHB Biochemical Assay. Human lactate dehydrogenase 1 (no.
A38155H, Meridian Life Science, Inc., Memphis, TN) was assayed as
described above for LDHA. Final concentrations in the 4 μL reaction
volume were 2 nM LDHB enzyme, 130 μM NADH, and 160 μM
sodium pyruvate.我需要购买哪些试剂以及如何设计实验?以下是我查到的销售的LDHA的蛋白LDHA

Background 背景The protein encoded by this gene catalyzes the conversion of L-lactate and NAD to pyruvate and NADH in the final step of anaerobic glycolysis.The protein is found predominantly in muscle tissue and belongs to the lactate dehydrogenase family.Mutations in this gene have been linked to exertional myoglobinuria.Multiple transcript variants encoding different isoforms have been found for this gene.The human genome contains several non-transcribed pseudogenes of this gene
该基因编码的蛋白质在厌氧糖酵解的最后一步催化 L-乳酸和 NAD 转化为丙酮酸和 NADH。该蛋白质主要存在于肌肉组织中,属于乳酸脱氢酶家族。该基因的突变与劳力性肌红蛋白尿有关。已发现该基因编码不同亚型的多个转录变体。人类基因组包含该基因的几个非转录假基因
