3. Project location: Jinfeng Laboratory

4. Procurement method: inquiry

2. Procurement content

3. Business requirements

1. Delivery time: Complete all experiments and data analysis work and complete acceptance within 30 days after signing the contract；

2. Service location: Jinfeng Laboratory, No. 313 Jinyue Road, Chongqing High-tech Zone；

3. Payment method: Settlement will be processed after the completion report is delivered and accepted, and the entire payment will be paid in one go after formal settlement.

4. Total project price limit: The total price quoted shall not be higher than the limit price of 199,800 yuan. The quoted price is a comprehensive lump sum price, including all equipment fees, software fees, installation fees, testing fees, travel expenses, freight, material fees, taxes, etc. The purchaser will not pay other fees separately.

4. Project requirements

Undertake the following core research tasks:

1. Screening and preparation of tumor samples - build a mass spectrometry testing platform, select samples of multiple tumor subtypes with high incidence and malignancy for testing, and select tumor subtypes with good significance and obvious markers.；

2. Development of mass spectrometry data classification and detection system - accumulate a large amount of tumor sample data, integrate multiple data analysis methods, develop a data analysis system based on clinical tumor mass spectrometry data, establish a tumor characteristic marker database, and realize information identification and qualitative analysis functions of characteristic markers；

3. Confirmation of marker metabolism process - Screen suspected tumor mass spectrometry markers based on mass spectrometry detection data, analyze their specific roles in metabolic pathways, explain the mapping relationship between markers and tumor diseases from the perspective of metabolomics, and provide data basis for tumor margin identification algorithms；

4. Standardized management of sample testing - Based on the diversity and complexity of samples, formulate standardized management requirements for sample screening, traceability, transportation, storage and other aspects.

5. Supplier qualification requirements

(1) Meet the qualifications of Article 22 of the "Government Procurement Law of the People's Republic of China":

Suppliers should send the quotation list and relevant attachments (which must be stamped with the official seal and scanned in color) to the contact email zhangpeipei@jflab.ac.cn before the inquiry deadline. Those who do not quote before the inquiry deadline will be deemed to have automatically given up.

Supplier quotation documents should include the following attachments (see Part 2 for details):

(1) Quotation letter；

(2) Quotation list；

(3) Legal representative qualification certificate (if the bidder is an authorized representative, he must also provide a legal representative authorization letter)；

(4) Copy of business license or other organization certification documents；

(5) Statement；

(6) Letter of commitment；

7. Requirements for signature and sealing of quotation documents

1. The bidder should prepare a freshly stamped quotation document (PDF) and send it to the email address. The quotation document must be clearly visible, otherwise the quotation will be deemed invalid.

2. The quotation document should be produced in accordance with the requirements of the "Inquiry Announcement". The quotation document must be signed and sealed by the legal representative of the bidder or his authorized representative at the prescribed signature place. The signature, seal and content should be complete. If there are any omissions, you will bear the risk of being regarded as an invalid quotation.；

3. The quotation document should be written clearly and neatly. Any insertions, alterations, additions or deletions between the lines must be signed or stamped with a personal seal by the legal representative of the bidder or his authorized representative.
