This product may be used with less than 20 mg of tissue if sample preparation volumes are reduced proportionally. For example, 10 mg of tissue may be extracted with 50 µL of nicotinamide adenine dinucleotide extraction buffer instead of 100 µL. Normalization to total protein is not expected to be necessary. The available information does not establish a minimum tissue amount or validation for corneal or ocular tissue.

General description
Pyridine nucleotides play an important role in metabolism and, thus, there is continual interest in monitoring their concentration levels. Quantitative determination of NAD+/NADH has applications in research pertaining to energy transformation and redox state of cells or tissue.
Pyridine nucleotides, including nicotinamide adenine dinucleotide (NAD), are crucial in cellular metabolism, impacting how energy is processed and managed within cells. Monitoring the concentrations of NAD and its reduced form, NADH, is vital for understanding cellular energy dynamics and redox balance. NAD, functioning as a central electron carrier, alternates between NAD+ (oxidized) and NADH (reduced) forms, facilitating numerous metabolic reactions. This transformation is essential not only for redox reactions but also for other metabolic functions, such as ADP-ribosylation, which is crucial for regulating protein functions and DNA repair. Additionally, NAD+ acts as a substrate for sirtuins, which are important for energy metabolism and modulating oxidative stress. .

Biochem/physiol Actions
The NAD+/NADH assay kit is based on a lactate dehydrogenase cycling reaction, in which the formed NADH reduces a probe into a highly fluorescent product. The fluorescence intensity of this product, measured at λEx = 530 nm/λEm = 585 nm, is proportional to the NAD+/NADH concentration in the sample. This assay is highly specific for NAD+/NADH with minimal interference (<1%) by NADP+/NADPH and is a convenient method to measure NAD, NADH and their ratio.
Features and Benefits
Broad Detection Range: Detect NAD and NADH levels accurately across a wide range, from 0.02 to 1 μM, using only 50 μL of sample in a 96-well plate setup, ensuring comprehensive analysis with minimal sample requirement
Simplified Process: Experience a streamlined process with the addition of only a single working reagent and a 10 minute room temperature reaction, reducing complexity and saving valuable time and effort.
Compatibility with High-Throughput Systems: Easily incorporate our kit into high-throughput handling systems, ensuring smooth and accurate processing, enhancing efficiency in your laboratory workflow.

Has MAK460 been validated for corneal/ocular tissue? Can the protocol be scaled below 20 mg for a single rabbit cornea, and what is the minimum tissue amount? Should NAD+ be normalized to tissue weight or total protein?

The protocol says "Determination of both NAD and NADH concentrations requires extractions from two separate samples". For cultured cells is it best to split a sample evenly into 2 to determine NAD and NADH or use 2 separate populations?
1 answer-
Provided there is sufficient sample volume for both the NAD and NADH determination, samples may be split to run each. Please see the following link to review additional information available in the product datasheet:

At the end of sample preparation, can we store the supernatants in either -20 °C or -4 °C and use the supernatants later for this assay so that we can wait until we accumulate 96 samples for 96 wells?
1 answer-
Yes, samples may be stored for at least 1 month at -80 °C following neutralization - see step 5 of the kit protocol provided at the link below:

Can I use this kit on an already isolated mitochondria sample (using a different kit to isolate from brain tissue), or is this kit only viable on tissue that is homogenized in NAD+/NADH extraction buffer? Thank you!
1 answer-
This kit has not been validated for use with isolated mitochondria samples. However, the procedure for a discontinued NAD+/NADH assay kit suggests that mitochondria should be lysed in the Extraction Buffer included in this kit and then deproteinized using a 10 kDa spin column. Alternatively, 2% CHAPS in TBS (25 mM Tris, 0.15M NaCl; pH 7.4) may be used to lyse the purified mitochondria. Vortexing the pellet for 1 minute followed by centrifugation at high speed for 2 minutes will yield a supernatant containing soluble mitochondrial protein. A similar procedure may be applicable for testing isolated mitochondria samples with this product.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers.

Can a white plate be used instead of a black plate for this assay?
1 answer-
A black, opaque, flat-bottomed plate is recommended for fluorescence assays, and a black plate with a clear bottom is also acceptable. White plates are not recommended for fluorescence assays as they can increase background and cross-talk. An example of a recommended plate type for fluorescence assays is the product M9685.

Does this assay measure total NAD+/NADH concentrations? If so, How can the conversion to NAD+ or NADH only be achieved?
1 answer-
The calculation method is the same for NAD+ and NADH. However, there should be one well for the NAD+ test and another well for the NADH test. If the intention is to solely measure NAD+, the sample should be processed according to the NAD+ instructions. This involves homogenizing the sample with NAD+ extraction buffer, then proceeding with heating and addition of the assay buffer followed by the addition of the opposite buffer (in this case, NAD extraction buffer). The order of addition of the extraction buffers determines whether NAD+ or NADH is being measured, as it degrades the other due to the extraction pH.
