A validity control, which contains common adulterants, is utilized in drugs of abuse (DOA) testing to confirm a laboratory's DOA analytical systems are performing accurately and can identify adulterated urine specimens. Validity Controls Level 1 through 5 are used as quality control materials to help identify substituted, diluted, and adulterated urine samples. The matrices for this QC are prepared from distilled water. The levels of the Adulterants, Creatinine, Specific Gravity, and pH are adjusted to the desired range for each lot prepared. Quality control before, during, and after the preparation of the control material ensures that each lot is comparable and of the same high quality. The listed ranges were verified by analytical methods similar to those actually used in a testing laboratory.

Our 100% Real Normal Human Serum is collected in FDA-licensed facilities within the United States from healthy adult donors. We screen our Normal Human Serum for common drugs of abuse and alcohol. Our frozen serum is suitable for all testing methods, including LCMS, LC-MS/MS, GCMS, Time of Flight (TOF), ELISA, EMIT and other immunoassays. This product uses Potassium Oxalate as an anticoagulant and Sodium Fluoride for preservation.

Immunosuppressants are essential for successful organ transplants. Their drug concentrations must be routinely monitored to ensure optimal levels and patient compliance. Lower concentrations lead to transplant rejection; higher concentrations lead to severe adverse effects including Graft vs Host Disease.

For the purposes of drugs of abuse screening it is necessary to have a set of controls with high, intermediate and low drug concentrations. These cutoff controls allow identification of various levels of abuse.

Our 100% Real Whole Blood is collected in FDA-licensed facilities within the United States from healthy adult donors. We screen our whole blood for common drugs of abuse and alcohol. Our frozen blank whole blood is suitable for all testing methods, including LCMS, LC-MS/MS, GCMS, Time of Flight (TOF), ELISA, EMIT and other immunoassays. This product uses Potassium Oxalate as an anticoagulant and Sodium Fluoride for preservation.

Anticonvulsant, or anti-epileptic drugs, are used to treat a wide range of symptoms affecting the nervous system. Most commonly they are utilized to control convulsive seizures, psychotic behavior and pain. Many of these drugs have very narrow therapeutic ranges and low thresholds for toxicity, meaning precision and accuracy are of the utmost importance. Our serum controls for anticonvulsants are an integral part of quality control for any lab that performs therapeutic drug monitoring.

There are two types of Vitamin D. Vitamin D2 (ergocalciferol) is obtained from food. It is metabolized by liver to its active form 25 hydroxycalciferol [25 OHD2]. Vitamin D3 (cholecalciferol) is synthesized in skin by sunlight's UV rays. It is metabolized by liver to 25 dihydroxycalciferol [25 OH D3] is involved in many biochemical functions including calcium and bone metabolism regulation. Vitamin D deficiency is associated with Ricketts, osteomalacia, depression and impaired cognitive function. Elevated Vitamin D levels decrease depression. High-dose vitamin D3 is also used to prolong remission intervals in multiple sclerosis (MS) patients.

Many toxicological specimens are whole blood. This control confirms a method's accuracy for quantitating heavy metals associated with poisoning in whole blood.

Trace elements are essential compounds necessary for a wide variety biochemical reactions including oxidation-reduction, synthetic and metabolic processes. They are a required cofactor for many enzymes. Trace element deficiencies associated with a failure of those enzyme systems for which the element serves as a cofactor cause biological system failures and death. Trace element toxicity is associated with overdose, usually secondary to taking too much high dose trace element supplements.

Our 100% Real Human Urine is collected from healthy donors within the United States. We screen our urine for the following analytes: d-Amphetamine, d-Methamphetamine, Benzoylecgonine (BE), (-)-Cotinine, Morphine, Oxazepam, and (l)-9-Carboxy-11-nor-Delta-9-THC (THC-COOH). Our liquid urine contains Sodium Azide for preservation and is suitable for all testing methods, including LCMS, LC-MS/MS, GCMS, Time of Flight (TOF), ELISA, EMIT and other immunoassays.

Do you find the synthetic chemicals a waste? Would you want to sell them to someone who need? BOC Sciences can offer solutions to such matters. This Turn Waste Chemicals into Wealth platform is launched to address the issue of resource waste especially for universities and institutes who synthesize chemicals for researches and studies purpose but have no way to deal with the left compounds that won’t be needed by their projects anymore, reversely, researchers that search for cost effective supplies or chemicals with rare access in the commercial market can benefit from such sharing. With this platform, the used to be waste chemicals can be granted with more scientific significance and can help to build a more environmental-friendly research world. BOC Sciences has tens of thousands of customers worldwide. Meanwhile, you can earn extra money through selling the synthetic chemicals which were considered as waste before.

Western blotting is an important technique for molecular biology. The researchers are detecting their specific proteins from a mixture of proteins extracted from the cells by using western blotting. The technique uses three important steps: separation theproteins by the size, transfer to membrane and detect target protein using a primary and secondary antibody. Nepenthe’s Rapid Bright (Transfer Immunoassay Detection) TID Plus Pack is designed to conveniently provide reagentsneeded for western blotting. The reagents in this kit are thoroughly validated with primary antibodies and ensuring accurate andreproducible results. This kit includes sufficient reagents and blotting membrans-papers to run 5-10-20 blots and complete western blot assays with our high quality secondary antibody. Easy Western Wash Buffer and transfer buffer included in this kit ensuresthat you get the most accurate results in your experiment.
