Stability & Storage

Dry ice transportation. Store in the dark at -20℃ or below, with a validity period of 12 months.

Background

The UA-Glo Kinase Luminescent Detection Kit can quantitatively determine the activity of kinases in enzymology experiments. This kit measures the kinase activity by quantitatively detecting the amount of remaining ATP after the kinase reaction: the amount of remaining ATP is negatively correlated with the kinase activity. When using this kit, the maximum ATP concentration in the kinase reaction can be up to 10μM; when using the UA-Glo Kinase Plus Luminescent Detection Kit, the maximum ATP concentration in the kinase reaction can be up to 100μM; and when using the UA-Glo Kinase Max Luminescent Detection Kit, the maximum ATP concentration in the kinase reaction can be up to 500μM. This kit can detect most kinases, and kinase substrates include polypeptides, proteins, lipids, or sugars, etc. The kit can be used for high-throughput homogeneous screening of kinase inhibitors, and can distinguish between ATP-competitive and non-competitive inhibitors by adjusting the ATP concentration.

Components

Product composition: Luciferase, luciferin, and buffer are mixed and filled into 10 ml or 100 ml brown bottles. The specifications are as follows:

Protocol

1. Kinase reaction
1)    Perform kinase reactions in 96-well or 384-well white opaque assay plates. It is recommended that the reaction volume for 96-well plates be 50μL and that for 384-well plates be 10μL. Test compounds with concentration gradients can be added to the kinase reactions.
2)   The concentrations of kinases and substrates in kinase reactions need to be optimized according to different kinases. Under the condition of the appropriate signal-to-noise ratio required for the experiment, the kinase concentration within the linear response range of the signal can be used for the experiment.
3)  Concentration of ATP: The maximum concentration detectable by the UA-Glo Kinase Plus Luminescent Assay Kit can reach 100μM.
4)   Kinase reactions can be performed in a universal reaction buffer (40 mM Tris-HCl (pH 7.5), 0.1 mg/ml BSA, 20 mM MgCl₂) or using reaction buffers and cofactors reported in the literature.
5)   The temperature and time of the kinase reaction need to be set according to different kinases. When conducting compound high-throughput screening experiments, it is recommended to optimize the kinase reaction to be carried out at room temperature (22℃-25℃) to help maintain the temperature uniformity of the assay plate during the kinase activity determination process.

2. Kinase activity assay
1)   Take out the UA-Glo Kinase Plus Luminescent Assay Reagent and equilibrate it to room temperature. Shake gently to mix. The luciferase reaction in the kinase activity luminescent assay reagent is sensitive to temperature changes; the reagent and the assay plate need to be equilibrated to room temperature, and the temperature should be kept constant (±1°C) during the test.
2)   If the kinase reaction is carried out at a non-room temperature, such as 30°C, the assay plate needs to be equilibrated to room temperature.
3)   Add 50 µL of kinase luminescent detection reagent to a 50 µL 96-well assay plate, or 10 µL of kinase luminescent detection reagent to a 10 µL 384-well assay plate, shake to mix well, and place in the dark for 10 minutes.
4)   Read the fluorescent signal. Since the fluorescent signal is very stable, if necessary, the plate can be read within 3 hours after adding the detection reagent.

Guidelines

1) It is not recommended to arbitrarily change the amount of reaction reagents without strict verification. The volume ratio of the kinase reaction to the UA-Glo kinase luminescent detection reagent should be 1:1.

2) After using the UA-Glo Kinase Luminescent Detection Reagent for the first time, it should be aliquoted and stored at -20°C to ensure the stability of the reagent. There is no loss of signal intensity after 4 repeated freeze-thaw cycles.

3) This product is for research use only.

Sparkle easy tarpaper towels gets the job done
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1), Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
Performs as described. Not as durable as Bounty but is worth the money. It is soft. Appearance is noted with a design. The quantity is appropriate for each roll and for the price. I use for clean ups in the kitchen, light spills and clean ups. Would buy again. Have purchased many many times. Reliable and consistent company the towel tear off easily every 8” which is a great way to avoid waste especially when cooking.

I'm going back to Sparkle
Package Size Name: Triple, Size: 3 Triple Rolls (Pack of 1)
I used to buy Sparkle years ago , it was the only brand I bought, but I stopped because they were lower quality than names like Bounty. Recently, before payday I ran out of paper towels and bought this pack before payday so I didn't have to shell out $25 for paper towels. Sparkle i can honestly say has improved immensely in quality, yet still staying reasonably priced. I noticed as soon as I opened one roll it was better quality. They are stronger, much stronger than they used to be. No loose lint like they used to have. They are a bit stiffer in feel compared to Bounty, but still feel soft. Cleaning is the real test for me. The old Sparkle shredded apart as soon as I wet the towel to clean. The new Sparkle is amazing. Gotta say I like it better than Bounty. I used it to clean the bathroom and the towels held up extremely well with being water soaked, used to scrub (friction & pulling). They don't feel thick which i like. Reusable? I'd dunk the towel in water, scrub then rinse the towel and wipe and it held up . Sparkle has improved and won me over!

Great value.
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
Excellent value for the money. They are not the most thick or soft. But they are better than some. It’s a good middle of the road towel. A very durable paper towel for various odd and end cleanups.

House staple
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
These Sparkle Pick-A-Size Paper Towels are a great everyday household staple. I really like the pick-a-size option because it helps reduce waste when you only need a small sheet for quick cleanups. The towels are absorbent, durable, and strong enough for kitchen messes, spills, counters, and general household cleaning without falling apart easily. They also tear cleanly and fit standard paper towel holders well. The rolls lasted longer than expected thanks to the smaller sheet option. Overall, a dependable and budget-friendly paper towel choice to keep stocked at home.

Decent Quality, Will Buy Again
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
I recently picked up the Sparkle Pick-A-Size Paper Towels (6 pack) and overall I’m pretty happy with them. The pick-a-size feature is really convenient because you can tear off a smaller sheet for quick spills instead of wasting a full one. For everyday kitchen messes—wiping counters, small spills, or drying hands—they work perfectly well. They’re also reasonably absorbent and the rolls seem to last a decent amount of time, especially when using the smaller sheet sizes. For the price, it feels like a good value compared to some of the more expensive brands. The reason I’m giving 4 stars instead of 5 is that they’re not quite as thick or strong as the premium paper towels out there. For bigger or really messy cleanups, I sometimes end up using two sheets. Overall though, these are a solid everyday paper towel that get the job done and help reduce waste with the pick-a-size option. I’d definitely buy them again.
