The expression of cloned genes under the control of the lac operon is induced by IPTG. It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. IPTG (Isopropyl-ß-D-thiogalactopyranoside) is a galactose analogue not recognized by ß-galactosidase. IPTG is a non-metabolizable galactose analog that induces expression of … IPTG is a lactose-mimic which binds to the lac repressor to enhance expression of the lac Z gene Synonym: Isopropyl-β-D-Thiogalactopyranoside Isopropyl-β-D-thiogalactopyranoside (IPTG) JavaScript seems to be disabled in your browser.

Protein expression was induced with IPTG and further optimized through The protein consists of 283 amino acids and had a molecular weight of 31.1 kDa and 

SKU. I-1312. CAS:367-93-1; Formula :C9H18O5S; MW:238.3 Da; Appearance:White crystalline powder; Purity:>99%  CAS: 367-93-1. Molecular Formula: C9H18O5S.

Isopropil-β-D-1-tiogalattopiranoside, abbreviato IPTG, è una molecola biologica non metabolizzabile, con la particolarità di essere un analogo dell'allolattosio, usata per indurre l'espressione dei geni sotto il controllo dell'operone Lac in E.coli.

Why should you use a 2.4 ml volume for these calculations rather than the 3.4 ml volume that will be used in the specific activity (velocity) calculation?

A fimbria is a proteinaceous appendage in many gram-negative bacteria that is thinner and shorter than a flagellum. Entered by. Activity. T7 polymerase is extremely promoter-specific and transcribes only DNA downstream of a T7 promoter. The T7 polymerase also requires a double stranded DNA template and Mg 2+ ion as cofactor for the synthesis of RNA. Molecular weight: 408.6. Form.

The recombinant plasmid was transformed into BL21 (DE3) competent cells and induced with IPTG. After induction, a specific protein band that is consistent with the theoretical molecular weight of FnCpf1 was detected in SDS-PAGE (Figure 2).

SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis. TEM: transmission electron microscopy. VLP: virus-like particle Studies investigating the subcellular localization of periplasmic proteins have been hampered by problems with the export of green fluorescent protein (GFP). Here we show that a superfolding variant of GFP (sfGFP) is fluorescent following Sec-mediated transport and works best when the cotranslational branch of the pathway is employed.

White crystalline powder.

Synonyms: IPTG (Isopropyl-beta-D-Thiogalactopy: CAS#: 367-93-1: Molecular Weight: 238.31: Molecular Formula: C 9 H 18 O 5 S: Shelf Life: 1 year: Ship Temperature: C: Storage Temperature

This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce E.coli protein expression where the gene is under the control of the lac operator. IPTG is supplied as a white crystalline powder, molecular weight 238.3. Quality Control In accordance with QIAGEN’s ISO-certified Quality Management System, each lot of IPTG is tested against predetermined specifications to ensure consistent product quality. Product Use Limitations IPTG is intended for research use. IPTG known as Isopropyl-β-D-Thiogalactopyranoside functions as an inducer of galactosidase activity by binding to and inhibiting the repressor.

White crystalline powder. IPTG, Isopropyl β-D-1-thiogalactopyranoside, binds the lac repressor and induces expression of β-galactosidase in E. coli . IPTG is Molecular Weight: 238.3.
