BACKGROUND

The T7 tag is an 11 amino acid peptide (MASMTGGQQMG) derived from the leader sequence of T7 bacteriophage gene10 which encodes a T7 major capsid protein. The T7 tag serves as a tag in many expression vectors, and antibodies specific for the T7 tag are useful for identifying and isolating T7-tagged proteins.

SPECIFICATION SUMMARY

Antigen: T7 (MASMTGGQQMG) conjugated to KLH.

Host Species: Goat

Specificity: Antibody was affinity-purified on the peptide.

APPLICATIONS

Immunoblotting: use at a dilution of 1:1,000- 1:20,000.

Immunocytochemistry: use at a dilution of 1:100-1:400.

Immunoprecipitation: use 1-4ug/mg lysate. ELISA: for detection use at a dilution of 1:1,000-1:30,000; for coating use at a dilution of 1:100-1:500.

These are recommended dilutions. Endusers should determine optimal dilutions for their applications.

Detection of T7-tagged fusion protein in 200, 100, and 50ng of E. coli lysate with #18862 diluted 1:25,000.
