HEK293 Cells
Form/Format
1x Sample Buffer (1x modified RIPA buffer+1x SDS loading buffer).
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
Sequence Positions
380aa
Sequence
Met1-Ser385
Applicable Applications for DPEP1 cell lysate
Western Blot (WB)
Application Notes
WB: Use at an assay dependent dilution.
Species
Human
Recommend Usage
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200uL pure water and boil for 2-5 min.
Sequence Construction
A DNA sequence encoding the human DPEP1 (P16444) (Met1-Ser385) was expressed with a polyhistidine tag at the C-terminus.
Preparation Method
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Preparation and Storage
Store at 4 degree C for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80 degree C for up to twelve months. Avoid repeated freeze-thaw cycles.
Samples are stable for up to twelve months from date of receipt.
Related Product Information for DPEP1 cell lysate
Dehydropeptidase-I, also known as DPEP1, is a kidney membrane enzyme. Its expression in normal colonic mucosa is very low, but it is highly expressed in colorectal adenoma and cancer specimens and is negatively correlated with parameters of pathological aggressiveness and poor prognosis. The overexpression of DPEP1 suppressed tumor cells invasiveness and increased sensitivity to chemotherapeutic agent Gemcitabine. Growth factor EGF treatment decreased DPEP1 expression. Dehydropeptidase-I may be a candidate target in PDAC for designing improved treatments. It uses zinc as a cofactor and acts as a disulfide-linked homodimer.

This Human DPEP1 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of DPEP1 protein from the overexpression lysate was verified.

NCBI Description

The protein encoded by this gene is a kidney membrane enzyme involved in the metabolism of glutathione and other similar proteins by dipeptide hydrolysis. The encoded protein is known to regulate leukotriene activity by catalyzing the conversion of leukotriene D4 to leukotriene E4. This protein uses zinc as a cofactor and acts as a disulfide-linked homodimer. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jan 2012]

Uniprot Description

DPEP1: Hydrolyzes a wide range of dipeptides. Implicated in the renal metabolism of glutathione and its conjugates. Converts leukotriene D4 to leukotriene E4; it may play an important role in the regulation of leukotriene activity. Belongs to the peptidase M19 family.

Protein type: Protease; EC 3.4.13.19; Membrane protein, GPI anchor

Chromosomal Location of Human Ortholog: 16q24.3

Cellular Component: extracellular space; microvillus membrane; apical part of cell; apical plasma membrane; plasma membrane; cell junction; nucleus

Molecular Function: protein binding; metalloexopeptidase activity; zinc ion binding; dipeptidyl-peptidase activity; caspase inhibitor activity

Biological Process: glutathione metabolic process; xenobiotic metabolic process; arachidonic acid metabolic process; leukotriene metabolic process; homocysteine metabolic process; negative regulation of caspase activity; proteolysis; negative regulation of cell migration; antibiotic metabolic process; negative regulation of apoptosis

Product Notes

The DPEP1 dpep1 (Catalog #AAA8115199) is a Cell Lysate produced from HEK293 Cells and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 380aa. AAA Biotech's DPEP1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). WB: Use at an assay dependent dilution. Researchers should empirically determine the suitability of the DPEP1 dpep1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Met1-Ser38 5. It is sometimes possible for the material contained within the vial of "DPEP1, Cell Lysate" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
