RPI L24030-500.0 LB Agar Low Salt Powder 500g Laboratory Grade

Description

Product Overview

RPI L24030-500.0 LB Agar is a premium low‑salt agar formulated specifically for life‑science laboratories that require reliable gel media for protein work. The product comes as a fine powder, weighing 500 g, and is designed to dissolve easily in standard preparation volumes, delivering a uniform gel matrix with minimal variability. Its composition includes 5 g/L sodium chloride and 10 g/L casein peptone, providing the essential nutrients and ionic balance needed for the growth of a wide range of microorganisms while preserving the integrity of delicate protein samples. The low‑salt formulation reduces background interference in downstream analytical techniques such as electrophoresis, western blotting, and mass spectrometry, making it an ideal choice for researchers who demand high‑quality results. Each batch is manufactured under strict quality‑control protocols by Research Products International (RPI), ensuring consistency across lots and compliance with industry standards for laboratory reagents.

Usage

This agar is suited for a variety of applications, including routine microbiological plating, selective growth of natural proteins, and specialized assays that involve casein peptone as a carbon source. Laboratories can prepare the medium by dissolving the powder in distilled water, heating to boiling, and allowing it to solidify in petri dishes or culture tubes. The low‑salt nature of the agar makes it particularly valuable in experiments where ionic strength must be tightly controlled, such as enzyme kinetics studies, protein crystallization trials, and cell‑free expression systems. It is also compatible with a range of supplements, antibiotics, and indicator dyes, enabling customized formulations for selective media or diagnostic tests. The product’s stable shelf life and convenient 500 g packaging reduce the need for frequent reordering, supporting continuous workflow in busy research environments.

FAQ

What is the advantage of low‑salt agar for protein research?

Low‑salt agar minimizes the presence of excess ions that can interfere with downstream analytical techniques such as electrophoresis, mass spectrometry, and enzyme assays. By reducing background ionic strength, the agar helps preserve the native state of proteins, leading to clearer results and more accurate quantification. This is especially important when working with delicate or low‑abundance proteins where even small amounts of salt can cause precipitation or alter activity.

Can I add antibiotics or other supplements to this agar?

Yes, the formulation is designed to be versatile. Researchers can incorporate a variety of antibiotics, selective agents, or indicator dyes without compromising gel integrity. Because the base medium has a low ionic concentration, added supplements dissolve uniformly, allowing precise control over selective pressure or visual detection of microbial growth. It is recommended to filter‑sterilize heat‑labile additives before adding them to the cooled agar.

How should I store the powder to maintain its quality?

The powder should be kept in a cool, dry place, preferably in a sealed container to protect it from moisture and contaminants. Storing at room temperature away from direct sunlight is sufficient; however, for extended storage periods, refrigeration (2‑8 °C) can further preserve its stability. Always check the expiration date and avoid exposing the product to extreme temperatures or humidity, which could affect its performance.

Is this agar suitable for large‑scale preparations?

Absolutely. The 500 g package is ideal for both small‑scale laboratory use and larger batch preparations required for high‑throughput screening or industrial research. The powder dissolves readily in water, and the low‑salt formulation scales linearly, ensuring that the same quality and gel characteristics are maintained regardless of preparation volume. Users can prepare multiple liters of medium in a single batch, reducing preparation time and resource consumption.

What support does RPI provide if I encounter issues?

RPI offers comprehensive technical assistance, including protocol optimization, troubleshooting guidance, and formulation advice. Customers can contact the support team via email or phone, and the company also provides detailed product datasheets, safety data sheets, and application notes on its website. This level of support helps ensure that users can quickly resolve any challenges and get the most out of the agar in their specific research applications.
