Description

HEK 293 HCPs (HEK 293 host cell proteins) ELISA Kit

The HEK293 HCP (Host Cell Protein) ELISA Kit is specifically developed for the quantitative measurement of host cell protein contamination in HEK293 cell lines. This kit offers exceptional sensitivity and accuracy, ensuring precise and reliable results for research purposes.Host cell proteins are contaminants that can be introduced during the production of recombinant proteins in mammalian expression systems, such as HEK293 cells. These proteins can impact the purity, safety, and efficacy of biopharmaceutical products, making their detection and quantification vital in ensuring product quality.

By using the HEK293 HCP ELISA Kit, researchers can effectively monitor and quantify host cell protein levels in cell culture supernatants and lysates, enabling them to optimize production processes, maintain product quality, and comply with regulatory requirements. This user-friendly kit is suitable for a variety of applications in cell culture and bioprocessing research.

Recovery: Matrices were spiked with HEK 293 HCPs(HEK 293 host cell proteins) and the recovery rates were calculated by comparing the measured value to the expected amount of HEK 293 HCPs(HEK 293 host cell proteins) in samples. Enquire for more information.
Linearity: The linearity of the kit was assayed by testing samples spiked with appropriate concentration of HEK 293 HCPs(HEK 293 host cell proteins) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected. Enquire for more information.
CV(%): Intra-Assay: CV<8%
Inter-Assay: CV<10%

When carrying out an ELISA assay it is important to prepare your samples in order to achieve the best possible results. Below we have a list of procedures for the preparation of samples for different sample types.

Sample TypeProtocol
Serum If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.

If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.

PlasmaCollect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit.
Urine & Cerebrospinal FluidCollect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid.
Cell culture supernatantCollect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately.
Cell lysatesSolubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Tissue homogenatesThe preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C.
Tissue lysatesRinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Breast MilkCollect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles.
