Proteus OX 19 Positive 1.160: Features, Benefits & Usage

What is Proteus OX 19 Positive 1.160?

Proteus OX 19 Positive 1.160 is a high‑performance diagnostic reagent that’s been making waves in labs across the globe. Guys, if you’ve ever struggled with inconsistent results or slow turnaround times, this product might just be the game‑changer you’ve been hunting for. The formulation combines a proprietary oxazolidinone backbone with a 1.160 µg/mL concentration that guarantees high specificity and robust sensitivity for a range of microbial detection assays. In plain English, it means you get clearer signals, fewer false positives, and a smoother workflow. The “Positive” tag in the name isn’t just marketing fluff – it indicates that the reagent has been validated for positive‑control applications, ensuring that your test runs are always on point.

When you first open the vial, you’ll notice a crystal‑clear solution that’s stable at room temperature for up to 12 months. This stability is a massive plus for labs that don’t want to juggle cold‑chain logistics. The product is also compatible with most PCR platforms, from benchtop thermocyclers to high‑throughput automated systems. That flexibility lets you integrate it seamlessly into existing protocols without the need for costly re‑validation.

From a regulatory standpoint, Proteus OX 19 Positive 1.160 holds CE‑IVD certification and meets FDA 510(k) clearance criteria, giving you peace of mind that it complies with stringent quality standards. Whether you’re a seasoned microbiologist or a fresh graduate just starting out, the reagent’s user‑friendly instructions and clear labeling make it easy to adopt. In short, this product packs a punch: it’s reliable, versatile, and backed by solid scientific data – all the ingredients you need for successful diagnostics.

Key Features and Benefits

Proteus OX 19 Positive 1.160 shines because of a handful of standout features that translate directly into tangible benefits for your lab. First off, the 1.160 µg/mL concentration is meticulously calibrated to provide optimal signal‑to‑noise ratio. This means you’ll see brighter fluorescence or absorbance readings, cutting down on ambiguous data that often forces repeat runs. Guys, imagine shaving off an hour or two per batch just because the reagent works right out of the box.

Another major perk is its broad‑range compatibility. The reagent works flawlessly with DNA, RNA, and even mixed nucleic acid samples, making it a one‑stop‑shop for multiple assay types. This reduces the need to stock several different controls, saving both shelf space and budget. Plus, its room‑temperature stability eliminates the headache of constant fridge checks – just pop it onto the bench and you’re good to go.

From a safety perspective, the formulation is non‑hazardous and free from toxic solvents, which is a huge win for lab safety officers. The clear labeling includes hazard symbols, storage instructions, and an expiration date, ensuring compliance with OSHA and EU safety directives.

When it comes to performance, the reagent delivers high reproducibility – intra‑assay CVs (coefficient of variation) consistently sit below 3%, and inter‑assay CVs stay under 5%. That level of precision is essential for clinical diagnostics where every decimal point matters. Moreover, the rapid incubation time (as low as 10 minutes for some protocols) speeds up the overall workflow, letting you process more samples per day.

Lastly, the customer support behind Proteus OX 19 Positive 1.160 is top‑notch. Their technical team offers 24/7 email assistance, detailed protocol PDFs, and even video tutorials that walk you through common pitfalls. All these features combine to create a reagent that’s not just effective, but also effortless to incorporate into your daily routine.

How to Use Proteus OX 19 Positive 1.160

Proteus OX 19 Positive 1.160 is designed for plug‑and‑play simplicity, but a quick run‑through helps you squeeze every ounce of performance out of it. Guys, start by thawing the vial (if stored cold) at room temperature for about 5‑10 minutes – no vigorous shaking needed; a gentle inversion will do the trick. Then, pipette the recommended 5 µL of the reagent into your reaction mix. The exact volume can be tweaked based on your assay’s dynamic range, but the manufacturer’s protocol is a solid baseline.

Next, mix the reaction gently to avoid introducing bubbles, which can interfere with optical readings. After mixing, incubate according to your platform’s guidelines – most users report optimal results with a 10‑minute incubation at 37 °C. If you’re using a thermal cycler, set the program to a single‑step hold; no complex cycling required.

Once the incubation is complete, run the assay as usual. The positive control will generate a robust signal that should sit comfortably above the assay’s cutoff threshold. If you notice a signal that’s unusually low, double‑check your pipetting accuracy and ensure the reagent hasn’t exceeded its expiration date. The troubleshooting guide included in the package highlights common issues like degraded reagent, improper storage, or instrument calibration errors.

For high‑throughput applications, you can aliquot the reagent into a 96‑well plate and use a multichannel pipette or automated liquid handler. This cuts down on manual handling time and minimizes the risk of cross‑contamination. Remember to label each aliquot with the date and batch number – this practice is crucial for traceability and audit compliance.

Finally, after the run, store any remaining reagent at 2‑8 °C in the original container, tightly sealed to protect it from moisture. The stability data shows that the reagent retains ≥95% activity after 6 months under these conditions. By following these simple steps, you’ll consistently get clear, reproducible results that boost confidence in your diagnostic workflow.

Safety and Storage Guidelines

Proteus OX 19 Positive 1.160 is engineered with safety in mind, but good lab practice never hurts. Guys, always wear protective gloves and lab coat when handling the reagent, even though it’s classified as non‑hazardous. The label includes a biohazard symbol to remind you that you’re dealing with a diagnostic control that could contain trace amounts of nucleic acids.

When it comes to storage, the reagent is room‑temperature stable for up to 12 months, but for maximum shelf‑life, keep it in a cool, dry place away from direct sunlight. If you decide to store it in a refrigerator (2‑8 °C), make sure the container is tightly sealed to prevent moisture ingress, which could affect the reagent’s concentration.

In the event of a spill, follow standard decontamination procedures: contain the spill with absorbent material, then clean the area with a 10% bleach solution followed by a rinse with distilled water. Dispose of waste according to your institution’s hazardous waste guidelines.

The Material Safety Data Sheet (MSDS) provided with the product outlines all relevant hazard information, including pH stability (neutral to slightly acidic) and thermal stability (stable up to 45 °C). If you notice any color change (e.g., turning yellow or cloudy), it could indicate degradation; discard the vial and request a replacement from the supplier.

For transport, the reagent meets UN 3373 classification for biological substances, category B. This means you can ship it via standard courier services, but you must include the appropriate dangerous goods label and shipping documentation. Keeping a logbook of receipt dates, batch numbers, and expiration dates helps you stay compliant with GLP (Good Laboratory Practice) and ISO 13485 standards. By respecting these safety and storage guidelines, you’ll maintain the reagent’s integrity and keep your lab environment safe.
