The Primary NK Transduction Kit is a complete kit suitable for primary NK cell engineering using viral transduction. It contains engineered Growth-Arrested NK Feeder Cells (#78912), Frozen Human Peripheral Blood NK Cells (#78798), NK Medium, Serum-Free (#82615), NK Cell Culture Cytokine Cocktail (#82616), and NK Viral Transduction Enhancer (#82617). The kit was optimized using high titer anti-CD19 CAR lentiviruses (such as BPS Bioscience #78601). The kit provides enough components for transduction of a starting population of more than 1 million NK cells.

Glyceraldehyde-3-Phosphate Dehydrogenase (GAPDH) (EC1.2.1.12) Glyceraldehyde-3-phosphoric acid catalyzed oxidation produce 1,3-diphosphate glyceric acid, is the key enzyme of glycolytic pathway, It is closely related to gluconeogenesis pathway, maintenance of blood glucose concentration in the body and the occurrence of diabetes, and plays an important role in the disorders of sugar, lipid and protein metabolism. CheKine™ Micro Glyceraldehyde-3-Phosphate Dehydrogenase (GAPDH) Activity Assay Kit can detect animal and plant tissues, cells or bacteria, culture solution or other liquid samples. In this kit, 3-phosphoglycerate kinase catalyzes the formation of 1,3-diphosphoglycerate from triphosphoglycerate and ATP. GAPDH reversely catalyzes 1,3 diphosphoglyceric acid and NADH to produce glyceraldehyde 3-phosphate, inorganic phosphorus and NAD+. The decrease of NADH measured at 340 nm can reflect the level of GAPDH activity.

Lipid hydroperoxide (LPO) is a peroxide produced by the action of unsaturated fatty acid chains by free radicals or reactive oxygen species. In pathological conditions, the enhancement of lipid peroxidation can lead to the increase of the originally low level of LPO. The increase of LPO content will cause damage to the structure and function of cells, and LPO content is closely related to the immune system and aging. CheKine™ Micro Lipid Peroxidation (LPO) Content Assay Kit can be used to detect biological samples such as animal and plant tissue, cells, plasma, serum or other liquid samples. In the kit, LPO is heated under acidic conditions to produce malondialdehyde (MDA), which condense with Thiobarbituricacid (TBA) to produce the brown-red substance trimethicine (3,5,5-trimethyloxazol-2,4-dione), whose maximum absorption wavelength is 532 nm. The content of LPO in the sample can be estimated by colorimetry.

L-galactose pathway is the main pathway of plant ascorbicacid (AsA) synthesis. L-galactose glucoside-1,4-lactone dehydrogenase (L-Galactono-1,4-Lactone Dehydrogenase, Gal LDH) is located in the mitochondrial membrane, responsible for the final step of the catalytic AsA biosynthesis in plants, is one of the key enzyme of the way. It plays a crucial role in the accumulation of AsA content in plants. CheKine™ Micro L-Galactono-1,4-Lactone Dehydrogenase (Gal LDH) Activity Assay Kit can detect plant tissues In this kit, Gal LDH catalyzed L-galactolactone reduction and oxidation of cytochrome C (Cyt c), and the reduced Cyt c had an absorption peak at 550 nm. Gal LDH activity was calculated by measuring the rate of increase of reduced Cyt c.

Ploygalacturonase (PG) (EC 3.2.1.15) is a kind of pectinase, which is widely found in plants, bacteria and fungi. It catalyses the decomposition of polygalacturonic acid, which plays an important role in fruit softening, pollen pollination, seed maturation and organ shedding. In addition, when pathogenic bacteria infect host plants, they can secrete polygalacturonase to degrade host cell wall, thus leading to the development of disease. CheKine™ Micro Ploygalacturonase (PG) Activity Assay Kit can be used to detect biological samples such as plant tissue, bacteria,fungus, liquid samples. In the kit, PG hydrolyzes polygalacturonic acid to produce galaturonate, which has a reducing aldehyde group, reacts with DNS reagent to produce reddish-brown substance, and has a characteristic absorption peak at 540 nm. The activity of polygalacturonase can be calculated by measuring the change of absorption value at 540 nm.
