AbFRONTIER's selection of bacterial and insect cell protein expression systems provides choices for your application. Standard service includes start-to-finish purification by our experienced scientific staff, to meet customers specific needs.
Solubility and binding test service available on a small scale to identify the most optimizing purification conditions for protein purification after large quantity E.coli culture by evaluating the protein expression and protein solubility.
AbFRONTIER Service Features
  Time and cost savings by pre-evaluating the solubility or creating purification environments after mass-cultivation.
  Identifying the most suitable condition is easy because transformation of four different kinds of E.coli is done when provided with DNA sample.
  Period: 2-3 weeks

Client Requirements
  - DNA > 0.5 ㎍ or cell stock > 100 ㎕
  - Client's test results (More prompt service is possible when the result is provided)

Protocol
  1. DNA transformation (when necessary)
  2. E.coli culture 20 ㎖
  3. Solubility test
    i. Cell harvest
    ii. Cell disruption : binding buffer by the cell lysis, sonication and centrifugation
    iii. Electrophoresis : Samples before supernatant and centrifugation
    iv. When soluble, conduct binding test; for his-tagged protein of the insoluble,
    conduct binding tests using denatured form (using urea).
  4. Binding test
    i. Tagged protein : Affinity column chromatography
    ii. Intact protein : Ion exchange chromatography
As baculovirus expression system, solubility and binding test service available on a small scale to identify the most optimizing purification conditions for mass protein purification by evaluating the protein expression and protein solubility.
AbFRONTIER Service Features
  Time and cost savings possible because purification can be made easier after mass-cultivation,
  or by checking if purification can be done at all.
  Period: 2-3 weeks

Client Requirements
  Baculovirus stock > 1x 107 pfu/㎖ x 3 ㎖

Protocol
  1. Baculovirus preparation
  2. Infection of insect cells (High Five cells)
  3. Solubility test
    i. Cell harvest
    ii. Cell disruption : binding buffer by the cell lysis, sonication and centrifugation
    iii. Electrophoresis : Samples before Supernatant and centrifugation
    Electrophoresis : Samples before Supernatant and centrifugation
    iv. When soluble, conduct binding test; for his-tagged protein of the insoluble,
    conduct binding tests using the denatured form (using urea).
  4. Binding test
    i. Tagged protein : Affinity column chromatography
    ii. Intact protein : Ion exchange chromatography
