A multifunctional electrolyte additive for lithium-ion battery: ethoxy-(pentafluoro)-cyclotriphosphazene
2022-02-15

High safety and high environmental adaptability are the basic requirements for the electrolyte of lithium-ion power batteries. With the continuous improvement and update of electrode materials, the requirements for corresponding electrolytes are also stricter. Because it is very difficult to develop a new type of electrolyte system, the common electrolyte of carbonate solvent and lithium hexafluor...
Preparation of N-[Tris(hydroxymethyl)methyl]-3-aminopropanesulfonic acid (TAPS)
2022-02-15

TAPS is a widely used zwitterionic buffer in the fields of biochemistry and molecular biology with pH buffer range from 7.7 to 9.1, and is soluble in water (25g/50ml). It can be used as biobuffer in clinical diagnosis, such as biochemical diagnosis kits, DNA/RNA extraction kits, and PCR diagnostic kits. The molecular structure of TAPS is as follows: At present, there are few reports on the synthes...
Preparation of Tricine-SDS-PAGE Gel
2022-02-15

Tricine is a zwitterionic buffer for biochemistry and molecular biology, with a pH buffer range of 7.4-8.8. During SDS-PAGE to seperate small peptides, tricine is commonly used instead of glycine in the Laemmli buffer. Tricine-SDS-PAGE gel has superior performance for the identification of proteins with molecular weight below 10 kd. While conventional SDS-PAGE is used to separate these proteins, s...
Preparation methods of guanfacine hydrochloride
2022-02-15

Guanfacine hydrochloride is a selective alpha-2A adrenergic receptor agonist for the treatment of moderate to severe hypertension. It can also be used for the treatment of attention deficit hyperactivity disorder (ADHD). It is suitable for children and for adolescent that stimulant is not suitable, or invalid. Here we describe several methods for the synthesis of guanfacine hydrochloride and compa...
Guanidine Hydrochloride or Urea—Which is a Better Protein Denaturant?
2022-02-15

In general, guanidine hydrochloride and urea can be used as protein denaturant. Guanidine hydrochloride and urea are generally used to obtain an estimate of protein conformational stability (the difference between proteins in their native and denatured states). Is the result obtained using these two denaturants consistent? Let's take a look at the results of Monera et al. [1]. Although urea and gu...
GOOD’s Buffers——PIPES and HEPES
2022-02-15

Good’s buffer is especially dedicated to life science research that does not participate in and does not interfere with biochemical processes. Here we introduce two commonly used Good’s buffers PIPES and HEPES. PIPES PIPES has a pH buffer range from 6.1 to 7.5, is insoluble in water, but soluble in aqueous NaOH. PIPES differs from buffers containing bis(2-hydroxyethyl)amino groups (such as Bis-tri...

2018-03-22

The 15th CACLP EXPO was closed on March 20, 2018 at the Chongqing International Expo Center. The exhibition attracted more than 800 exhibitors. They shared the products, industry news etc. for the attendees in the area of IVD. And Suzhou Yacoo Science Co., Ltd is one of exhibitors. This IVD exhibition is a grand gathering of IVD reagents production and management, logistics and application, inform...
Bis(2-hydroxyethyl) amine Family Buffers
2018-03-20

The bis(2-hydroxyethyl)amine family buffers includes Bis-Tris, BES, and Bicine. Brief introduction of these three buffers are as follows. Bis-Tris Bis-tris is a zwitterionic buffering agent with pH range from 5.8 to 7.2. Bis-tris forms stable complex with Cu2+ and Pb2+ and a weak complex with many common metals, so formation constants should be taken into account when using this buffer in a soluti...
