CD300A Protein, Cynomolgus, Recombinant (Avi), Biotinylated

Catalog No. TMPK-00560

CD300a is an inhibitory receptor for mast cells and eosinophils in allergic inflammation (AI); however, the spatiotemporal expression of CD300a and its potential roles in the resolution of AI are still to be determined.CD300a expression on peritoneal cells is regulated from inflammation to resolution. CD300a activation on mouse bone marrow-derived mast cells regulated ALX/FPR2 expression levels following IgE-mediated activation. CD300A Protein, Cynomolgus, Recombinant (Avi), Biotinylated is expressed in HEK293 mammalian cells with C-Avi tag. The predicted molecular weight is 19.44 kDa and the accession number is A0A7N9CE79.

Questions

QWhat should I do if the IC50 obtained for cell killing are significantly different from that presented on the your website?

AThe IC50 you obtain refers to the cell proliferation inhibition assay (half maximal inhibitory concentration), which is different in meaning from the IC50 on our website. The IC50 often refers to the inhibition rate of the target without cell experiments, which is generally determined through kinase or protein purification experiments, and is commonly reported in nanomolar concentrations. However, the IC50 obtained from cell proliferation inhibition assays refers to the half-maximal lethality of the cells, which involves cellular metabolism and penetration, so the concentration is usually higher. Furthermore, the effect of the same compound on different cell models varies. It is recommended to try increasing the incubation volume and extending the incubation time.

QWhat do "mg/mL" and "mM" mean?

Amg/mL" and "mM" are two different units of measurement, but represent the same maximum solubility. You can convert between them using the molar concentration calculator on our website.

QHow to dilute working solutions?

ACalculate the dilution factor and volume of the stock solution needed based on the concentration of your working solution. It is recommended to use solvents such as water, saline solution, PBS, or culture medium for dilution. For cell experiments, culture medium is suitable. Slowly add the appropriate solvent to the stock solution until you reach the desired concentration of your working solution. Gentle vortexing or pipetting can help mix the solution evenly. Most of our compounds are lipophilic, and precipitation may occur when using PBS or culture medium to dilute the working solution. It is normal and the product can usually be completely dissolved by sonication. It is recommended to prepare and use the working solution immediately after dilution

QWhat should I do if the products in powder form adhere to the vial tightly?

AIt's recommended to centrifuge it at 3000 rpm for a few minutes.

QAnimals cannot tolerate DMSO well. How should the dosage of DMSO be controlled during administration?

AFor normal mice, the concentration of DMSO should be kept below 10%. For nude mice, transgenic mice, or mice with weak tolerance, the concentration of DMSO should be kept below 2%. For inhibitors being used for the first time, it is recommended to perform a solvent-negative control experiment to confirm that the solvent has no nonspecific effects on the animals.

Biological Activity	Activity has not been tested. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first.

Synonyms	Pigr4,NKRL,Mcipr1,MAIR-I,LMIR1,IRp60,IRC1,IGSF12,CLM-8,CLM8,CD300a
Construction	Leu18-Gln178
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	19.44 kDa (predicted). Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.
Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research Background	CD300a is an inhibitory receptor for mast cells and eosinophils in allergic inflammation (AI); however, the spatiotemporal expression of CD300a and its potential roles in the resolution of AI are still to be determined.CD300a expression on peritoneal cells is regulated from inflammation to resolution.
