| LRRC15

Leucine rich repeat containing 15 is a cell membrane-expressed protein. In humans it is encoded by the LRRC15 gene.It is located on chromosome 3 at 3q29. It belongs to the LRR superfamily, which is involved in cell–cell and cell–ECM interactions.It is an inhibitory accessory factor for SARS-CoV-2 cell entry. LRRC15 lacks obvious intracellular domains. LRRC15 displays a highly restricted expression pattern, but is expressed in areas that make up innate immune barriers such as the placenta, skin, activated fibroblasts in wounds, and lymphoid tissues such as the spleen.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	20	10	5	2.5	1.25	0.625	0.312	0
OD	2.52	1.96	1.38	0.97	0.55	0.31	0.19	0.08
Corrected OD	2.44	1.88	1.3	0.88	0.47	0.23	0.11	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Human LRRC15 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-101	94
Cell Lysates(n=8)	94-105	102

 

| Linearity

Samples were spiked with high concentrations of Human LRRC15 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-95	86-96
	Average (%)	91	93
1 : 4	Range (%)	89-103	87-108
	Average (%)	95	98
