3. E. coli guaranteed packages

The E. coli guaranteed packages have the following features:

i) The customer provides the plasmid or the expression strain; or the gene is synthesized by Bio Basic for an additional charge.

ii) The size of the target protein is usually <100KDa.

iii) In some rare cases, in order to facilitate expression, Bio Basic may try different tags and the final protein product may contain such tag.

iv) The final purified protein is tag-containing.

v) Bio Basic does not guarantee the endotoxin level of the purified protein.

vi) If Bio Basic fails to deliver the guaranteed amount due to the nature of the protein or other unpredictable circumstances, only the set up fee will apply.

4. Protein purification packages

The protein purification packages have the following features:

i) The customer provides the plasmid or the expression strain; or the gene is synthesized by Bio Basic for an additional charge.

ii) The size of the target protein is usually <100KDa.

iii) In some rare cases, in order to facilitate expression, Bio Basic. may try different tags and the final protein product may contain such tag.

iv) The final purified protein is tag-containing.

v) Bio Basic does not guarantee the endotoxin level of the purified protein.

vi) If Bio Basic fails to deliver the guaranteed amount due to the nature of the protein or other unpredictable circumstances, only the set up fee will apply.

5. Functionality of purified protein

Bio Basic cannot guarantee activity or functionality of any purified protein. Bio Basic can, however, guarantee purity of a special protein depending on the package chosen.

6. Protein analysis

Standard QC methods include SDS-PAGE and Western Blot (if desired). Western-blot can only analyze seven samples each time in addition to controls and markers. Bio Basic will provide one free Western-blot analysis. If customer requires more than one, extra charges will apply. Bio Basic will provide the primary anti-His-tag antibody. If an antibody other than the anti-His-tag antibody is required, the customer needs to provide Bio Basic with the specific antibody. There are many factors affecting Western-blot analysis, Bio Basic cannot guarantee that there is not a false positive/negative result. If the result is abnormal, Bio Basic can provide another Western-blot analysis free of charge.

7. Proteins that fail to be expressed and purified

Bio Basic makes its best effort to express and purify the target protein. Should Bio Basic be unsuccessful in purifying the target protein (due to sequence instability, toxicity, hydrophobicity, etc.), the minimum 50%, non-refundable, start-up fee will apply.

8. Cancellations

For any protein, the customer may cancel the order after reaching an agreement with Bio Basic:

i) If Bio Basic has received the order but has not initiated the project; the customer is entitled to cancel of the order without any penalty.

ii) If Bio Basic has prompted protein expression and purification; the customer may cancel the order, however, the customer is obligated to pay a penalty cost depending on the stage or status of the project.

iii) If Bio Basic has obtained the target protein and completed the project; the customer may cancel the order, however, the full amount will be paid to Bio Basic.

9.Patents

Bio Basic serves as a service provider and offers synthesis service of sequences provided by the customer. It is the sole responsibility of customer to verify whether his respective work is the result of any infringements of any patents. Bio Basic. expressly disclaims any liability in this regard.
