We use a number of analytical techniques in-house to characterize our products including native and SDS-PAGE followed by a variety of staining methods, , protein concentration, endotoxin determination, KDO and phosphate analysis, a variety of binding assays, Western blot, ELISA, HPLC, thin layer chromatography, cell cytotoxicity assays, cytokine assays, fluorescent and colorimetric enzyme assays. For selected products, we have electrospray mass spectrometry (ESI-MS) performed to determine molecular weight.
Through contract services, we offer a highly sensitive assay to detect low levels of botulinum neurotoxin type A (BoNT/A) in complex matrices and diluted plasma. We also have a sensitive and specific assay for detection of anthrax lethal factor (LF) in plasma.
Due to our commitment to quality and the nature of our products, we are unable to accept returns.

Our price list indicates which items are Select Agents and Toxins. Link to the Federal Select Agent Program: http://www.selectagents.gov/ The Federal Select Agent Program is jointly regulated by the Centers for Disease Control and Prevention/Division of Select Agents and Toxins (CDC DSAT) and the Animal and Plant Health Inspection Services/Agriculture Select Agent Services (APHIS AgSAS). Although excluded amounts can be purchased outside of this program, certain purchases require the user to register with the Federal Select Agent Program and to obtain permission for each shipment.
A majority of List Labs products ship via FedEx both domestically and internationally. Select Agents & Toxins/Dangerous Goods are shipped via UPS domestically and via World Courier internationally.
We insure packages through the shipping carrier. If your institution has insurance you may request for the shipment not to be insured. However, our FOB (free on board) terms are Campbell, California, making the recipient liable for the package once it is in the hands of the carrier after it leaves our facility.
If payment will be by credit card or payment in advance you do not have to complete the credit section.

Comparison of Product Grades
If your institution would prefer that you not work with lyophilized toxins, we can reconstitute certain products for you. A nominal fee will apply, if your purchase is just a single vial. After reconstitution, the item ships on Blue Ice, and this increases transportation and box fees.
We offer three different formulations. Product #179A/B is provided frozen in a glycerol formulation. This product is already in solution and adds the convenience of being readily available for each use. However, shipping on blue ice is required, and it is not available internationally. Product #180 is provided lyophilized in sodium phosphate buffer. It is stable when shipped at ambient temperature and suitable for most applications. Product #181 is provided lyophilized without a buffer, which allows you reconstitute the pertussis toxin in the buffer of your choice.
Lethal dose 50% (LD50) is described in the following link: http://www.ccohs.ca/oshanswers/chemicals/ld50.html. We do not perform this assay, and LD50 is not provided for our products. If it is required, we will subcontract this work.
When it is feasible, we lyophilize our products to enhance the stability. Some of our products, though, lose activity upon freezing and are therefore not lyophilized or frozen. Our liquid products are shipped on dry ice or Blue Ice, which require prompt transportation and delivery. Storage conditions after receipt are provided on the Certificate of Analysis enclosed with each item that is purchased.
Most of our products are offered as a lyophilized powder which allows the item to ship at room temperature. Stability varies from product to product. The Certificate of Analysis reports stability data after reconstitution, if known. However, the product may have multiple applications, and stability varies for different applications.
Our products are for research purposes only and are not to be used in humans or as diagnostic agents. We do have capabilities to provide GLP or GMP products utilizing our contract manufacturing capabilities.
An online account is established for customers who wish to place their orders via our online ordering process. A new customer application is completed when the institution is placing an order at List Labs for the first time.
We provide same day shipping for most orders received before noon Pacific Standard Time. Orders arriving after noon ship the following business day.
Products requiring cold packaging ship Monday, Tuesday or Wednesday only due to the temperature requirements for liquids. They must be shipped via standard overnight or priority overnight.
For room temperature domestic shipments you may choose Standard Overnight (delivery to most locations by end of the next business day), Priority Overnight (delivery to most locations by 10:30 a.m. the next morning), or Economy Service which is a two day delivery.
Packages going to international destinations are shipped Federal Express International Priority. Some exceptions apply.
We prepay shipping fees and add the freight charges to your invoice, unless you provide your carrier’s account number when placing your order.
Generally, one to three business days.
If you would like to set this up we would be happy to help you. Please speak to a customer service representative about standing purchase orders.
A certificate of analysis is provided with each shipment. When it is a dangerous good that ships on a hazardous declaration an SDS also is included with the shipment.
Yes, however some products have additional requirements for international shipments.
Products shipped on Blue Ice or Dry Ice require a written statement from customers stating they agree to receive the products in the condition that they arrive. A simple line on a purchase order with the statement, “I agree to receive products shipped on ice in the condition they arrive.” will suffice.
Select Agents & Toxins can only be carried internationally via World Courier.
We can offer custom sizes. Some products allow us to do this easily and can be provided cost effectively. The larger the quantity desired, the more cost effective the project will be.
Some relationships with distributors are exclusive, while others are not. Please contact our customer service department with your specific location or review the distributor page.
