White Solid
Uses
Different sources of media describe the Uses of 35061-50-8 differently. You can refer to the following data:
1. An inhibitor of lysozyme, reverses myocardial depression and lessens norepinephrine requirements in Escherichia coli sepsis in dogs.
2. lectin inhibitor, immunopotentiator
3. Diacetylchitobiose/Chitobiose, a dimer of β(1,4) linked N-acetyl-D glucosamine, is used as an alternative source of N-acetylglucosamine by some bacteria. It is used in fermentation research to study, differentiate and characterize chitobiose transporter systems and enzymes such as β-N-acetylglucosaminidase(s) and chitobiose phosphorylase(s).
Biochem/physiol Actions
In chitinolytic bacteria, such as Vibrio, Streptomyces and Serratia, N,N′-Diacetylchitobiose (GlcNAc2) is not only a major breakdown product of chitinase, but it is also the smallest substance that induces chitinase production. It can also be utilized as a carbon source by E. coli, which does not express chitinases, but is exposed to GlcNAc2 produced by intestinal chitinolytic bacteria. In most organisms, the uptake of GlcNAc2 occurs via the phosphoenolpyruvate:glycose phosphotransferase system (PTS). GlcNAc2 has also been used as a substrate or inhibitor to study the activity of glycolytic enzymes.
Purification Methods
Recrystallise N,N'-Diacetylchitobiose from aqueous MeOH or aqueous EtOH/1,2-dimethoxyethane. [Zilliken et al. J Chem Soc 77 1296 1955, Beilstein 18/11 V 147.]
Check Digit Verification of cas no
The CAS Registry Mumber 35061-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,0,6 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 35061-50:
(7*3)+(6*5)+(5*0)+(4*6)+(3*1)+(2*5)+(1*0)=88
88 % 10 = 8
So 35061-50-8 is a valid CAS Registry Number.

experimental part, p. 688 - 695 (2010/08/07)
The gene of Serratia marcescens chitinase A(chiA) was cloned by PCR. The complete gene was constructed into a pRSET vector and expressed in Escherichia coli. The recombinant enzyme was purified to > 90% homogeneity by hydrophobic interaction chromatograph
