| PRB2

Basic Salivary Proline Rich Protein 2，also known as PRB2 or Recombinant Basic Salivary Proline Rich Protein 2 (Recombinant PRB2), is a type of recombinant protein. Recombinant Basic Salivary Proline Rich Protein 2 (PRB2) is a protein derived from human saliva, characterized by its high proline content. It belongs to the family of salivary proline-rich proteins, which play important roles in various biological processes, such as maintaining the stability of saliva and protecting oral tissues.
 

| 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)	10	5	2.5	1.25	0.62	0.31	0.15	0
OD	2.12	1.58	1.14	0.77	0.53	0.35	0.24	0.08
Corrected OD	2.04	1.5	1.06	0.69	0.45	0.27	0.16	-

 

| Repeatability

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

| Recovery

The recovery of Human PRB2 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Saliva(n=8)	84-101	96

 

| Linearity

Samples were spiked with high concentrations of Human PRB2 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Saliva(n=4)
1 : 2	Range (%)	84-95
	Average (%)	91
1 : 4	Range (%)	89-103
	Average (%)	94
