MASP2 Overexpression Lysate Summary

Description

MASP2 Transient Overexpression Lysate


Expression Host: HEK293T

Plasmid: RC218844

Accession#: NM_139208

Protein Tag: C-MYC/DDK

You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.
Gene
MASP2

Applications/Dilutions

Dilutions
  • Western Blot
Application Notes
This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
Theoretical MW
19 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Notes

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Background

The Ra-reactive factor (RARF) is a complement-dependent bactericidal factor that binds to the Ra and R2 polysaccharides expressed by certain enterobacteria. Alternate splicing of this gene results in two transcript variants encoding two RARF components that are involved in the mannan-binding lectin pathway of complement activation. The longer isoform is cleaved into two chains which form a heterodimer linked by a disulfide bond. The encoded proteins are members of the trypsin family of peptidases. [provided by RefSeq]

FAQs for MASP2 Lysate (NBP2-05582). (Showing 1 - 1 of 1 FAQ).

  1. We wish to measure MASP-2 levels in human plasma. Are stored plasma (or serum) at -20 centigrade stabile for this measurement if only frozen once. Should we measure in duplicate or triplicate? Is plasma better than serum as I have both stored for the MASP-2 test? What would be the cost of a kit and how many samples would it measure? I assume there is no special equipment other than ELISA like stuff? What is the shelf life as I have holiday next month? Is the a list of equipment we need to run the kits so I can check it with our lab technicians.
    • Once frozen samples should be fine for measurement. Generally, all experiments should be performed at least in triplicate so you can perform statistical analysis. MASP-2 should be detectable in both serum and plasma. Serum might yield cleaner signals since it is depleted of blood cells and clotting factors, but the depletion could, theoretically remove some MSAP-2 as well. Either type of sample should be suitable though. We currently have no MASP2 ELISA kits available. A list of our MASP2 antibodies can be found at this link if you would like to make your own. We guarantee all of our antibodies for 6 months from the receipt date.
