Lysate Details for Array

• Type: Overexpression

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.This product is manufactured by and sold under license from OriGene Technologies and its use is limited solely for research purposes.

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]. Transcript Variant: This variant (1) is the longer transcript and encodes isoform 1 that activates complement component 4.

FAQs for MASP2 Lysate (NBL1-12906). (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.
