Q：What is the difference between fetal bovine serum and newborn bovine serum?
Fetal cows are sampled from the embryo in the cow's belly, newborn cows are sampled within 0-24 hours of birth, and calves are sampled 10-14 days after birth.

Q：How does Li Ji Biology ensure the quality of premium fetal bovine serum FBS products?
Li Ji Biological FBS undergoes strict screening for each batch, requiring continuous three-layer 0.1um filter membrane filtration. The filter material meets the requirements of the US FDA document, and the entire production process conforms to international fetal bovine serum production. It also undergoes strict quality control and analysis and testing of physical, chemical, and microbiological indicators.

Q：How does the sensitivity of the four mycoplasma detection kits from Yuan Li Ji compare?
A4：1、 The detection sensitivity of the "probe method" is high, and its detection lower limit can reach 5.6-10.8 copies/2 μ L; 2. Next is the "PCR method", which has a higher detection sensitivity similar to or slightly lower than the "probe method"; 3. The detection sensitivity of the "rapid method" is lower than that of the "PCR method" and the "probe method", with a detection lower limit of approximately 22.5-172.3 copies/2 μ L; 4. The detection sensitivity of the "luminescence method" is the lowest, with a detection lower limit of approximately 2200 live bacteria/μ L at a dilution of 10 ^ (-3).

Q：What are the differences between the three transfection reagents used by Yuan Liji and Yuan Liji? How does it compare to Li * *?
A2: Our company conducted self testing and collected customer feedback data, and came to a similar conclusion: in terms of efficiency: EZ Trans Plus>Li * * 2000 ≈ EZ Trans (high efficiency)>Li * * 3000>EZ Trans (low toxicity). Toxicity: EZ Trans (low toxicity) ≈ Li * * 3000<EZ Trans Plus<EZ Trans (high efficiency) ≈ Li * * 2000.

Q：There are 3 types of ECL luminescent liquid, how to choose?
A1: There are three types of luminescent liquids with different sensitivities from Yuan Liji. The enhanced, ultra sensitive, and Fick level correspond to low Pic level, Pic level, and Fick level protein detection, respectively. They can completely replace PE, Millipore, or Thermo's corresponding products. Customers can choose according to the experimental situation, and Liji's best-selling type is the ultra sensitive type.
"Heyuan Liji" is a joint venture between Heyuan Biotechnology (stock code: 688238) and Liji Biotechnology, specializing in the "Liji Biotechnology" and "Life-ilab" reagent brands
