Expi293 gnti cells

Manufactured by Thermo Fisher Scientific

The Expi293 GnTi- cells are a genetically engineered cell line derived from human embryonic kidney (HEK) 293 cells. They are designed for efficient and high-yield transient protein expression. The cells feature a knockout of the GnT-I gene, which results in the production of proteins with homogeneous, non-fucosylated glycosylation patterns.

LILRB1, MDB1, and RIFIN Protein Production

Check if the same lab product or an alternative is used in the 5 most similar protocols
LILRB1 D3D4, antibody MDB1 and RIFIN genes were synthesized and subcloned (GenScript, NJ) into pVRC8400 vectors, with HRV3C cleavable His or Fc tag. DNAs of RIFIN with either LILRB1 or MDB1 were co-transfected into Expi293 Gnti- cells (Thermo Fisher) using Turbo293 transfection reagent (Speed BioSystems). Six days post transfection, culture supernatants were harvested, and affinity purified with cOmplete™ His-Tag Purification Resin (Roche) or protein A resin (GE) by following manufacture’s protocols.

LAIR1 and RIFIN Protein Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
LAIR1 (wild type and mutants), antibodies (MGC34, MGD21, MGJ5, MGM1) and RIFIN genes were synthesized and subcloned (GenScript, NJ) into pVRC8400 vectors, with HRV3C cleavable His or Fc tag. DNAs were transfected into either Expi293F cells or Expi293 GnTI- cells (Thermo Fisher) using Turbo293 transfection reagent (Speed BioSystems). Six days post transfection, culture supernatants were harvested, and affinity purified with cOmplete™ His-Tag Purification Resin (Roche) or protein A resin (GE) by following manufacture’s protocols.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
