At the American Society of Clinical Oncology (ASCO), researchers released the largest ctDNA assay ever.

The study performed ctDNA testing on 17,628 blood samples from 15,191 patients involving 50 tumor types. The results showed that the sensitivity of blood samples for tumor DNA was 86% (lung cancer), 83% (breast cancer), 85% (colorectal cancer) and 78% (other types of tumors).

The application of ctDNA in the field of cancer is being recognized by more and more clinical experts. As a result, more and more startups are pouring into the ctDNA field, and a number of listed companies (Hua Da Gene, WuXi PharmaTech, Daan Gene, Jin Yu Inspection, Livzon Group, Jingfeng Pharmaceutical, Fosun Pharma, Youxun Medicine, Gemma Gene, Baoteng Bio, etc.), New Third Board listed companies and more mature startup companies (after C round) are also in the field of ctDNA The depth layout.

Based on HSMAP, Flint created the “National ctDNA Company Patent Ranking”, “Domestic ctDNA Company Valuation Ranking” and “Domestic ctDNA Company Market Ranking” to reveal the number of patent layouts and competitions of major startup companies in the domestic ctDNA field. Happening.

"Domestic ctDNA company patents list"

Description:

1. This list is ranked according to the information published by relevant companies at home and abroad or the number of patents entering the review stage. Domestic patents do not include software copyrights;

2. This list does not include the following company categories:

Listed companies, New Third Board listed companies, startups after the C round, and companies with a small proportion of the ctDNA business in the total business;

3. If you have any doubts about this list, please feel free to contact Flint (you can also comment in the message area).

Potassium Tert-butoxide CAS No.865-47-4

Potassium tert-butoxide Basic Information
CAS: 865-47-4
MF: C4H9KO
MW: 112.21
EINECS: 212-740-3

Mol File: 865-47-4.mol

Potassium Tert-butoxide Structure

density 0.910 g/mL at 20 °C

Potassium Tert-butoxide Application

1. Used in pesticides, medicines, printing and dyeing, Catalysts, etc.
2. As a strong base, it is widely used in the condensation, rearrangement and ring opening reactions in organic synthesis such as chemical, pharmaceutical and pesticide.
3. It is a moderately strong base commonly used in organic synthesis.
4. The reason why t-BuOK is widely used is that it is inexpensive and readily available, and its basicity changes depending on the selected reaction solvent.
5. For Stobbe condensation, t-BuOK is a better base than EtONa, with higher reaction yield, shorter reaction time, and no side reactions of ketone or aldehyde reduction.
