EnzyFluo™ Farnesyltransferase Activity Assay Kit

What it means: The detection method tells you how this assay kit produces a measurable signal. The value shown here is Fluorescent (FL 340/550 nm), meaning the result is captured through a fluorescence-based readout with FL 340/550 nm capability.

How to interpret here: On this page, Fluorescent (FL 340/550 nm) is the instrument and readout requirement for the product, so your workflow should be planned around that mode and any stated wavelength settings.

Why it matters for buying:

• Buy this format only if your lab has hardware that can support Fluorescent (FL 340/550 nm) and the data type fits your reporting needs.
• The readout mode can influence background tolerance, sensitivity expectations, and how easily the assay fits matrices such as Biological Samples, Purified Enzyme.

Practical guidance:

• Confirm reader capability, filters, or wavelength settings before ordering, and qualify the method with blanks plus appropriate positive and negative controls in your own matrix.
• Use a short pilot run to verify that the signal stays linear and interpretable across the concentration or activity range you expect to study.

What to watch out for:

• Nominal instrument compatibility is not always enough; specific wavelength, filter, or optics constraints can still limit usability.
• Colored, turbid, or autofluorescent samples can shift the practical performance of the listed method even when the hardware matches.

What it means: Sample type describes the matrix this assay kit is intended to work with. The value shown here is Biological Samples, Purified Enzyme.

How to interpret here: For this product, Biological Samples, Purified Enzyme identifies the sample input for which the stated workflow and performance are most relevant; other matrices should be treated as an adaptation rather than assumed fit. That broad wording is useful for screening, but it still requires matrix-level verification in the exact sample class you plan to run.

Why it matters for buying:

• This is one of the quickest filters for deciding whether the product matches your specimen source without extra method development.
• Sample compatibility often has a larger impact on background, recovery, and dilution needs than the assay chemistry alone.

Practical guidance:

• Plan matrix-matched blanks or controls and run a small pilot study with the exact sample preparation approach you intend to use.
• Start with a small matrix comparison panel rather than assuming all biological materials will behave the same way.

What to watch out for:

• Broad sample labels can hide meaningful differences between fluids, lysates, extracts, and processed specimens.
• Moving from one matrix to another can change the practical range, sensitivity, and control strategy even when the analyte stays the same.

What it means: Species tells you the biological context this assay kit is intended to support. The value shown here is All species.

How to interpret here: On this page, All species should be read as the supported organism set or intended biological context for the assay, not as a blanket guarantee that every matrix from those species behaves identically. This usually points to an analyte or chemistry that is not limited to one organism, which is common for activity or metabolite assays.

Why it matters for buying:

• Broad species coverage is useful when one workflow must support multiple model systems or translational sample sets.
• This field is especially important when you compare results across organisms, tissues, or translational sample sets.

Practical guidance:

• Even with broad species coverage, verify recovery and dilution behavior separately in each sample matrix you care about most.
• Treat cross-species use as a qualification exercise: confirm baseline signal, dilution behavior, and recovery in the matrices you actually intend to run.

What to watch out for:

• Broad species coverage still does not guarantee identical behavior across every tissue type, treatment condition, or collection method.
• Even when the species field looks broad, unusual treatments, extraction chemistries, or disease matrices can still change performance.

What it means: Detection limit gives the lowest level this assay kit is intended to distinguish from background under stated conditions. The value shown here is 0.024 U/L. Here, the sensitivity is expressed in activity units, so it should be judged against the enzyme or activity levels expected in your samples.

How to interpret here: On this page, 0.024 U/L is most useful as a sensitivity benchmark when comparing options; the effective floor in your lab can still shift with instrument setup, matrix effects, and sample preparation.

Why it matters for buying:

• Choose a product whose limit is comfortably below the lowest result you expect to measure, rather than assuming a borderline value at 0.024 U/L will always be robust.
• Sensitivity should be considered together with sample compatibility and working range, not in isolation.

Practical guidance:

• Include low-level controls or standards near the expected cutoff and confirm dilution linearity in the exact matrix you plan to test.
• Treat readings near 0.024 U/L as candidates for replicate confirmation, especially when decisions depend on small differences close to baseline.

What to watch out for:

• Detection limit is not the same as the full quantifiable range or guaranteed performance in every sample type.
• Background from media components, blood-derived matrix effects, extraction buffers, or reader settings can raise the practical limit above the headline specification.
