120991-82-4 Usage
Uses
Transfer RNA (tRNA) has been used in in vitro probe transcription for in situ hybridization.
General Description
Transfer RNA (tRNA) are responsible for amino acid transport and the correct reading frame in protein biosynthesis. The knowledge of their tertiary structure and interactions with proteins and ribosomes is important for the understanding of mechanisms involved in protein biosynthesis. The tRNA is added as a competitor to pre- and hybridization solution to prevent nonspecific binding of the probe. This product is also tested for the absence of RNase according to the current Quality Control procedures. 1mg of dry substance corresponds to 21 A260 units.
Check Digit Verification of cas no
The CAS Registry Mumber 120991-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,9 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120991-82:
(8*1)+(7*2)+(6*0)+(5*9)+(4*9)+(3*1)+(2*8)+(1*2)=124
124 % 10 = 4
So 120991-82-4 is a valid CAS Registry Number.
