H19 Dye for DNA Relaxation and Supercoiling Assays

What it means: 1,000 assays — how many assays one pack supports.

Why it matters:

• The assay count helps you plan how many plates or samples one order covers.
• It lets you budget reagent for standards, blanks and repeats.
• Knowing the count helps you schedule reorders before you run out.
• Assay counts assume the recommended reaction volume per well.
• Planning the number of plates before ordering avoids running short mid-study.
• Assay counts help you compare reagent cost per data point.
• Counting assays per pack also helps you decide between pack sizes when more than one is offered.

For this product: One vial gives 1,000 assays in a 96-well plate format.

Tip: Dilute the 10 x H19 Dilution Buffer to 1x with water, then dilute the dye 1:1500 in the 1x buffer just before use.

What it means: 1500 x — the concentration of the supplied stock.

Why it matters:

• The stock concentration decides how far you dilute the product for each reaction.
• Knowing it lets you work out how many reactions one vial supports.
• Using the same final amount in every reaction keeps results comparable.
• A stated concentration makes dilution steps easy to record and repeat.
• It also helps you compare your conditions with published methods.
• Writing down the lot and stock concentration helps when you compare runs over time.
• Over-concentrated working solutions can raise background or waste material.

For this product: The dye is supplied as a 1500 x stock (170 µl).

Tip: Protect the dye from light and dilute it just before use.

What it means: Frozen — how the product is shipped.

Why it matters:

• The shipping condition tells you what to expect when the package arrives.
• Unpacking promptly lets you check the contents against the order.
• Checking the package on arrival helps you spot transport problems early.
• Storage conditions can differ from shipping conditions, so confirm them before the package arrives.
• Recording the arrival date and condition helps if questions come up later.
• Arranging for someone to receive the package avoids delays when it arrives.
• The shipping condition is chosen to keep the product as described during transport.

For this product: Ships frozen; unpack it promptly on arrival. Please contact us to confirm storage conditions.

Tip: Open and check the package on arrival, and contact us right away if anything is damaged or missing.
