*information only, for your orders, Go to each product page. 


The Fastest Transforming Cells Worldwide - 1 minute Transformation
 

• Fast transforming cells - exclusive technology
• 1 minute transformation

* With “ECOS™” standing for “E. Coli One-Step”, and its reverse “SOCE” standing for “SOC Eliminated”, the name itself speaks for the advantages.

* 1 minute, 1 step high-efficiency transformation and no SOC recovery step required, truly a design to save your time.

Transformation Protocol




 Special Tips 





Patented Technology

Yeastern Biotech Co., Ltd. owns the patent of ECOS™ technology (protocol) exclusively in USA, UK, Taiwan, and France (Patent No. US 6,864,088; GB 2383582; I 229696; FR 2832727, etc.). Under the protection of this patent, Yeastern Biotech is the only company that has the right to use the protocol with the claims that transformation with our ECOS™ chemically competent cells can be finished within one minute and SOC is not needed. If anyone intends to sell competent cells that use ECOS™ protocol or its similar version, please contact our headquarters in Taiwan for licensing.



Quality Control

Each lot of competent cells has to pass three quality control tests before shipping:

1. Efficiency test: each batch of ECOS™ should meet the claimed transformation efficiency at the time of production using Protocol 4 (Page 3-3) and supercoiled pUC19 DNA.

2. Contamination test: competent cells were plated directly on ampicillin plates without being transformed. To pass the test, no colonies should be seen after overnight incubation.

3. A-complementation test: this test is performed for all ECOS™ competent cells except for ECOS™ 21(DE3) and ECOS™ 2163. To pass the test, the ratio of white colonies over the total colonies should be less than 3%



=Q & A=

        A: 
          a.    One Step; Time-saving
          b.    Easy to operate 
          c.    No SOC recovery 
          d.    No tube change 

V.    Q: What is the shelf life of ECOS competent cells?
       A: One to One and a half years  

VI.    Q: During the thawing step of operating ECOS competent cells, how far does it need to be thawed?
         A: One half to Two-thirds thawed  

VII.    Q: If customers choose Kanamycin as antibiotics resistant gene screening, what suggestions should we inform them?
          A: Use SOC for Recovery 

VIII.    Q: How should we set the temperature and time when operating the step of Heat Shock?
           A: 42°C and Forty-five seconds 

IX.    Q: What is the achievable efficiency ranking of the four operation modes on the ECOS card?
         A: Three>One>Four>Two
   
X.    Q: When cultured to produce plasmids, which ECOS can be completed in as fast as 4 hours?
        A: ECOS™ SONIC™  

XI.    Q: When the colony is cultivated, we usually set different time according to the strain, also the time range is usually from four to sixteen hours, however, what is the fixed temperature should be set?
         A: 37°C

XII.    Q: What is the usual time and temperature for colony culture of ECOS™ 101 Competent Cells [DH5α]?
         A: 37°C and Twelve to Sixteen hours 

XIII.    Q: When Plasmid fragment>6kb, which kinds of ECOS competent cell is used ideal?
           A: ECOS™X, ECOS™101, ECOS 10B

XIV.    Q: How much will the efficiency be reduced if ECOSTM competent cells are thawed, dispensed, and refrozen repeatedly?
           A: If ECOSTM competent cells are thawed, dispensed in aliquots, and refrozen within 3 min, the transformation efficiency will be 20~50% less than first time use.

XV.    Q: Which the humidity of LB plate is good for the efficiency? Dry or Wet?
          A: Dry
